BT MBORC

Posted: Friday, December 9th, 2011 at 16:57 by Neil Watson

BT have declared MBORC (Matters beyond our reasonable control) in Scotland, Northern Ireland and Cumbria. The text of the notification is below:

“MBORC declaration: This MBORC declaration for Scotland, Northern Ireland and Cumbria is issued as a special alert to all BT Wholesale Customers/Communications Providers.

Following the recent severe weather in Scotland, Northern Ireland and Cumbria, we have today carefully reviewed the impacts on our operations and network. Most of our operations are back to normal, but may be affected by any further severe weather.

However, the BT network has been affected. Some parts of our overhead network were damaged in the storm. We are doing all we can to make the repairs, but we will need time to complete all the work. Our fault stacks in the affected areas are rising as we receive fault reports.

We are therefore declaring this as a Matter Beyond Our Reasonable Control (MBORC) incident with effect from 14.00 today, Friday 9 December 2011.

This declaration will apply to all faults caused by the exceptionally severe weather on Thursday 8 December 2011 across Scotland, Northern Ireland and in Cumbria. It won’t apply to other faults and it won’t apply to provision jobs. The affected areas are:

Highlands & Islands
North East Scotland
Tayside & Fife
South East Scotland
West Central Scotland
South West Scotland
Cumbria
Northern Ireland

We are implementing contingency plans to bring in additional resources so we can recover service as quickly as possible.”

  1. Neil Watson says:

    A further update has be received in relation to the MBORC:

    “Further to our original MBORC Declaration issued last week on 9th December 2011, we are continuing to experience severe weather conditions in a number of locations across the UK.

    In the north of the country, as notified in our MBORC declaration, storms seriously affected our network in the following areas

    Highlands & Islands
    North East Scotland
    Tayside & Fife
    South East Scotland
    West Central Scotland
    South West Scotland
    Cumbria
    Northern Ireland

    This MBORC declaration remains in place for faults caused by the storm damage, but does not cover provision activities.

    We, and our suppliers, continue to work to bring the fault levels back down to normal working levels, however we experienced major damage to our network in recent storms and as some of this damage is in the more isolated areas, this will take time to repair.

    We have increased our resource capacity in the affected areas through the use of overtime, movement of staff from unaffected areas and use of contractors. We continue to focus on repairing the network in these areas and will lift the MBORC as soon as we have been able to clear the affected faults.

    In addition to the issues in the North, the south of the country experienced high winds and rain last night. We are pleased to confirm that this has caused only limited damage to our network, however, fault volumes are slightly higher than normal and we expect this number will rise throughout the day. Plans are in place to manage these levels as they increase.

    Further, our suppliers have been engaged to ensure that sufficient resources and materials are being diverted to the affected areas, in the north of the country this has included delivery of 12Km of aerial cable and 290 new poles.

    We continue to monitor the weather closely as further possible heavy storms are forecast for later this week and this may impact our ability to move resource around the UK, however we are making every effort to minimise any disruption and will keep you informed as this develops.

    Fault volumes are likely to increase above the levels normally expected, however be assured that we will continue to focus on bringing these levels down to normal working levels across the country as quickly as possible.”

Traffic prioritisation measures

Posted: Tuesday, December 8th, 2009 at 15:37 by Steve Lalonde

On 2nd November 2009 we advised that, starting 4th November, Entanet was monitoring new traffic prioritisation measures for approximately three weeks. To remind yourself of the detail please see the NOC notice of 2nd November.

The feedback we have received strongly supports Entanet’s decision to continue to apply the measures as a means of improving the user experience of the majority of customers. As a result our prioritisation measures will continue to be applied. Where customers report access speed issues, we have encouraged Partners to share the experiences with us directly and with specific details so that we can investigate accordingly.

In addition to the Questions and Answers listed in our communication on 2nd November, please make note of the following:

Q: How is traffic prioritised?
A: In order to deliver a better user experience of interactive services, less priority across the DSL network will be given to non-interactive bulk services at times of congestion. However, there are no specific or hard set trigger points at which prioritisation is applied and released on the protocols. Compared to other communications providers that set specific and permanent maximum limits on speed of access to non-interactive bulk services irrespective of bandwidth availability, Entanet’s measures are applied dynamically and traffic types are given the highest possible speed according to their priority versus bandwidth availability in real time.

Q: What traffic types are considered non-interactive bulk services?
A: Peer-to-peer and newsgroups protocols are given lower priority as non-interactive bulk services.

Q: When is traffic prioritised?
A: It is important to note that the prioritisation measures are applied dynamically. This means that, whilst the prioritisation rules run 24/7, varying levels of speed restriction are applied to non-interactive bulk services as the demand for interactive services bandwidth increases. Consequently there may be times when no traffic prioritisation is taking place and all services enjoy a higher speed.

Q: Is the Anti-Loss Tool (ALT) being used?
A: No, the ALT, including the high bandwidth user marking system, is not in operation because we are applying the traffic prioritisation measures.

Please note these measures continue to be monitored and are subject to change.

MEASURES TO IMPROVE ENTANET BROADBAND SPEEDS

Posted: Monday, November 2nd, 2009 at 12:28 by Steve Lalonde

We have been monitoring traffic across the Entanet DSL network following increased feedback about poor connection speeds on our standard broadband packages, both in the charged and uncharged periods. We have identified that approximately 90% of customers are seeing their user experience adversely affected by approximately 10% of the customer base who are using their connection for non-interactive bulk services, for example news groups and peer-to-peer. Our aim is to deliver a positive user experience primarily for interactive services, for example web browsing, video streaming, VoIP and hosted application access.

In order to achieve this we will be applying techniques to give interactive services a higher priority across the DSL network. This action is in line with clause 2.5 of our Ts & Cs which refers to carrying out improvements, preventing overload of the network and preserving the integrity of the services. It is also being taken following consultation with several of our larger Partners. For the avoidance of doubt, we have so far not applied any protocol shaping or protocol prioritisation techniques.

Q: When will we start this?
A: We will begin prioritising traffic from 00:01hrs, Wednesday 4th November 2009.

Q: Is this action permanent?
A: We will monitor the impact of the traffic prioritisation for a period of approximately 3 weeks. If it is determined that this approach is successful then it is likely we will continue with this activity.

Q: Will we advise Partners of the impact of prioritising traffic in this way and whether it will become permanent?
A: Yes, aside from the overall improvement to service that we expect Partners and EUs to see as a result of our traffic prioritisation, we will seek feedback from Partners and confirm our decision on whether the measures will become permanent.

Q: How will it work?
A: Interactive services will be given higher priority across the DSL network. We do not intend or expect to impose any hard capping of specific protocols. This is unlike certain other communications providers who set permanent limits on specific protocols. Rather, we intend to dynamically manage traffic such that all services are available according to their priority. Therefore, varying levels of speed restriction will be applied to non-interactive bulk services where they adversely impact interactive services. It is not possible at this stage to identify specific parameters.

Q: Will Partners and EUs be able to see how traffic is being prioritised?
A: Not at the outset, although we will be considering if specific information can be provided in the future. In the meantime we will continue to provide details of our node utilisation on noc.enta.net.

Q: Will the existing Business and Family product prioritisation remain?
A: Yes, the current product attributes are unchanged.

Q: Will we advise Entanet-billed EUs directly?
A: No, as we are not introducing a product change we do not need to directly advise Entanet-billed EUs. However, this information is provided formally both on noc.enta.net and the e-billing site.

Q: What will happen to the Anti Loss Tool (ALT)?
A: During the period that we prioritise traffic as described above, the ALT (including the high bandwidth user marking system) will not be in operation.

Q: Will this affect EWCS customers?
A: No, our wholesale customers will not be impacted by this measure.

BT Openreach MBORC declaration

Posted: Tuesday, February 3rd, 2009 at 14:46 by Neil Watson

BT Openreach have declared a force majeure event in several areas. The text of the declaration is below:

MBORC declaration due to recent heavy snowfall

Following heavy snow fall Openreach is now declaring a matter beyond our reasonable control (MBORC) / force majeure event in some areas.

The declaration is effective from 09:00 am on Monday 2nd February 2009. It applies to all provision and repair activities caused by the severe weather conditions in the specified areas.

The recent heavy snowfall has impacted Openreach in two main ways. Firstly, the reduced mobility of our engineering workforce and, secondly, the reduced numbers of Openreach people able to get to our control centres. This resulted in a number of missed jobs and appointments where, whilst every effort was made to contact those end users, this was not always successful.

We have increased our engineering resource capability for the rest of this week, especially in those areas worst affected, and put our control centre contingency plans into operation. The impact on service, on a regional basis, is as follows and is based upon the current seven day weather forecast.

Scotland – impact seen in East of Scotland. We are working normally and full recovery is expected by 9th February 2009.

Northern England – impact seen in the Pennines, Tees Valley, Yorkshire and Lincolnshire. Full recovery is expected by 9th February 2009.

Midlands & Wales – impact seen in East & Central Midlands. Full recovery is expected by 9th February 2009.

London Home Counties – impact seen in London and the Thames Valley areas. Full recovery is expected by 10th February 2009. We have declared MBORC in the following areas: Basingstoke, City, Docklands, Guildford, Heathrow, Southbank, Wembley, Westend and Westminster.

South West – impact seen in Solent. Full recovery is expected by 10th February 2009.

South East – impact seen in Sussex, Kent North and South London. Full recovery is expected by 10th February 2009. We have declared MBORC in the following areas: Chelmsford, Crayford, Croydon, Edmonton, Esher, Greenwich, Lea Valley, Richmond, Romford, St Albans and Watford.

We will review this situation on a day-by-day basis and will lift the MBORC in each area as soon as service returns to normal. In addition, we continue to watch the weather and its impact and will advise should we need to declare MBORC in any other areas, or if our recovery times are extended as a result.

    Update: MBORC declaration due to recent heavy snowfall

    This update follows recent MBORC declarations on 2nd and 5th February 2009.
    Following heavy snow across the country this week, we have declared a matter beyond our reasonable control (MBORC) / force majeure event in some parts of the UK. This communication provides an update on locations where MBORC declarations have been lifted and on areas where MBORC has subsequently been declared.

    The impact on service, on a regional basis, is as follows:

    South East:

    The MBORC declaration was lifted at 08:00 today on all declared areas; Chelmsford, Crayford, Croydon, Edmonton, Esher, Greenwich, Lea Valley, Richmond, Romford, St Albans and Watford. MBORC will still to apply to any activities impacted by the weather that have not yet been resolved. This will be reviewed on a case-by-case basis.

    London & Home Counties:

    The MBORC declaration was lifted at 08.00 today for all the London patches; City, Docklands, Heathrow, Wembley, Southbank and Westminster. As above, MBORC will still apply to any activities impacted by the weather that have not yet been resolved.

    MBORC will remain in place in Basingstoke and Guildford.

    Following more snow, MBORC has now been declared, with effect from 08.00 Thursday 5th February 2009, in Maidenhead, Reading, Luton, Northampton, Oxford and Aylesbury.

    Further Openreach Update: MBORC declaration due to recent heavy snowfall

    This communication follows recent MBORC declarations, issued as special alerts to all Communications Providers, following heavy snow across the UK.

    Matter beyond our reasonable control (MBORC) / force majeure event has been declared in some parts of the UK. This communication provides an update on where we have been able to lift the MBORC declaration and on areas where MBORC has subsequently been declared.

    The current impact on service, on a regional basis, is as follows:

    South West – overnight snow and low temperatures have meant continuing bad road conditions. MBORC is currently in place in; Bristol, Bath, Swindon, Gloucester and Taunton. In addition, MBORC has now been declared, with effective from 08.00 today, in; Plymouth, Exeter, Salisbury and Bournemouth.
    Wales & Midlands – with effective from 08.00 today, MBORC has been lifted in Cardiff, Swansea and Peterborough.

    Scotland – continuing snow and low temperatures in the patches where we have open declarations. MBORC is currently in place in; Grampian, Highlands South (parts only), Highlands North (parts only), this MBORC has been extended to included a further 15 exchanges towards the west.

    London & Home Counties – conditions remain poor in many areas. MBORC is currently in place in; Oxford, Aylesbury, Northampton, Luton, Maidenhead, Reading, Basingstoke and Guildford.

    South East – the MBORC declaration was lifted at 08:00 today on all declared areas; Chelmsford, Crayford, Croydon, Edmonton, Esher, Greenwich, Lea Valley, Richmond, Romford, St Albans and Watford.

    Our expectation is that if we have no more snow, and road conditions improve, we will be able to recover by very early next week. In the meantime, we are continuing to review this situation, and the weather, and will keep you updated as we make progress.

  4. Neil Watson says:

    MBORC Update – 20 February

    This communication follows recent MBORC declarations, issued as special alerts to all Communications Providers, following heavy snow across the UK.

    Matter beyond our reasonable control (MBORC) / force majeure event has recently been in place in some parts of the UK. This communication provides the latest update.

    The impact of recent weather conditions varied across the UK. In some areas we were able to continue as normal, while others experienced extreme disruption. As a result, the declaration and lifting of MBORC was extremely complex and continuously changing. We are currently pulling together all of the information and will shortly provide you with a full report showing when each MBORC was declared and lifted.

    All declarations ended, at the latest, with effect from 12:00 Tuesday 17th February. At that time, the only open blanket declarations in place were for Grampian, Highlands South (part) and Highlands North (part).

IPStream Connect Status Tool

Posted: Tuesday, January 20th, 2009 at 14:45 by Neil Watson

Whilst network changes are taking place as previously advised on this site, it has become necessary to temporarily remove access to the IPStream Connect status tool. This is because the tool could present incorrect information at times when necessary changes to bandwidth availability are being made on an IPSC interconnect by interconnect basis. We aim to restore access to the tool as soon as possible and apologise for any inconvenience that this restriction may cause you.

Factors Affecting ADSL Performance

Posted: Monday, January 19th, 2009 at 20:05 by Neil Watson

Further to our communication on this site (http://noc.enta.net/?p=381) we write to explain the reasons for reduced performance over the past few days and to apologise for any inconvenience caused to customers. Please be assured that we are working to ensure normal service levels are resumed as soon as possible.

In our previous communication we advised that, as users re-authenticate in order to connect to the IPSC interconnect serving them, we expect user volumes and bandwidth demand to vary among the interconnects and to be unrepresentative of performance expected when all moved users are connected to IPSC. It is therefore possible that variable performance may be experienced, especially during off-peak hours, until such time that normal volumes are established.

The process of moving connections from IPStream Centrals to IPSC is being executed without issue. However, at the point of executing the move, it is not possible for Entanet to know which IPSC interconnect individual users will be connected to, as this information is not available from BT Wholesale. Furthermore, as complete execution of the move relies on users re-authenticating to establish their connection on the new interconnect, it has not been possible for us to estimate the total bandwidth required to serve them. It is not feasible for us to set an artificially high bandwidth level, as doing so commits Entanet to that level with BTW for a minimum 3 month period. Bandwidth usage is therefore being continuously monitored and adjusted as users re-authenticate.

Whilst managing an increase in bandwidth availability per interconnect it has also been necessary for Entanet to operate the Anti-Loss Tool (ALT) on IPSC as it does on IPStream Centrals, in order that all users receive service. However, in this unsettled period, at times the application of the ALT has uncharacteristically affected performance to a greater degree. Further incremental increases in the bandwidth level proved to successfully suspend the ALT, albeit only temporarily.

These affects are currently being experienced mainly in off-peak hours only. During peak daytime hours the available bandwidth results in some minor activation of the ALT. Nonetheless we regret that off-peak users have experienced differing performance levels than they are accustomed to and will continue to actively manage bandwidth to a successful conclusion.

DSL transfer to IPStream Connect update

Posted: Wednesday, January 14th, 2009 at 18:00 by Steve Lalonde

Further to the previous post, we have now moved the bulk of the remaining realms to IPStream Connect. Please be aware that end users need to re-authenticate in order to connect to the IPSC interconnect serving them (note that dropping the session for more than 30 seconds will be required to ensure the session is re-established on the new interconnects).  As users do so over the coming days, we expect user volumes and bandwidth demand to vary among the interconnects and to be unrepresentative of performance expected when all moved users are connected to IPSC. It is therefore possible that variable availability may be experienced, especially during off-peak hours, until such time that normal volumes are established. The ALT is operational on IPSC and will take effect whenever necessary as normal.

The interconnect graph will be adjusted to reflect the available bandwidth at each handoff (instead of a percentage of the maximum capable on the interconnect). Please note that, in the short term, the illustrated results are unlikely to be indicative of available capacity.
