Outage: Sheffield

Posted: October 14th, 2014 at 16:16 by David Derrick

We have lost connectivity to our equipment in Sheffield. Other traffic will reroute round the outage but services originating or terminating in Sheffield are currently down.

More details will follow when we know what has happened.

  1. David Derrick says:

    Service has been restored, the cause appears to be failure of power to the whole rack. Investigations are continuing into the root cause.

Planned Maintenance: Sonicwall GMS

Posted: October 14th, 2014 at 11:57 by David Derrick

Wed 22 October 2014 10:30-12:30 BST

During the above window the management system for our Sonicwalls will be upgraded. During this time, customers will be unable to view reports and our support staff will be unable to make changes.

The operation of the appliances themselves will be unaffected and urgent changes can still be made by the NOC team.

Since this is only a point release no loss of data is expected but full backups will be taken should we need to roll back.

  1. David Derrick says:

    This work is complete and GMS access for customers has been restored.

Internal Systems Issues

We are currently experiencing issues affecting access to many of our internal systems. This failure will impact the efficiency of our teams in being able to deal with your queries as access to certain information is currently unavailable. We ask that you please bear with us during this period and request your patience when dealing with the teams.

In addition to this partners will not be able to access our Synergi Portal.

We are working to rectify the situation as quickly as possible and will make a further post when systems are restored.

Power Maintenance: Interxion, London

Posted: September 18th, 2014 at 15:22 by David Derrick

Saturday 27 and Sunday 28 September 2014
Following conversations with Interxion management we have been advised that the rescheduled intrusive power upgrade is likely to take place over the above weekend with the non-critical feed being done on Saturday 27 and the critical feed being done on Sunday 28. Please note this is subject to official confirmation and we will post an update with full details when we receive the formal notice from Interxion.

  1. David Derrick says:

    Interxion have now confirmed the schedule for this weekend.

    On Saturday 27 September between 08:00 and 19:30 BST, the current non-critical feed will be upgraded to the new UPS B feed.

    On Sunday 28 September between 08:00 and 19:30 BST the current critical feed will be upgraded to the new UPS A feed.

    In both cases the power is expected to be down for a minimum of 1.5 hours but may be longer. When the power is restored, engineers will check the breakers on our feeds in case any trip when the power returns.

    Entanet’s equipment is all dual fed so we do not expect any outage to our services, however the site should be considered at risk during the maintenance windows.

  2. David Derrick says:

    Interxion have advised that today’s power work has been completed.

  3. David Derrick says:

    Interxion have advised that all the power upgrade work has now been completed.

Power Maintenance: Interxion, London

Posted: September 17th, 2014 at 11:34 by David Derrick

Saturday 20 September 2014 08:00 to 17:30 BST

Today we have received notification that Interxion will be performing the previously postponed intrusive power upgrade work on both critical and non-critical feeds during the above maintenance window.

The following is the notice received:
“All upgrade works will be undertaken by specialist contractors under the direct supervision of Interxion staff.

The works below are planned for Saturday 20th September. The upgrade works will consist of the non-critical electrical supplies being transferred onto new UPS system (feed ‘B’.) Following satisfactory confirmation of the transfer of the Non critical electrical supplies, we plan to transfer the critical loads onto new UPS system (feed ‘A’). Dual corded equipment if wired correctly should not be impacted. However, single corded equipment WILL be impacted.”

Entanet equipment has already been moved to dual fed supplies so will not be affected although the site should be considered at risk during the maintenance window. Colocated customers with single fed equipment will however be affected.

  1. David Derrick says:

    We have been advised that Interxion are postponing the work planned for this weekend. We will post details of the new schedule when we have more details.

Power blip at Telford HQ

Posted: August 26th, 2014 at 16:55 by Neil Watson

We have recently lost power at our Telford Headquarters for approximately 5 minutes. This was due to a high voltage fault in the local area that affected 170 properties. During the failure our backup generators took the load and services remained in operation as normal. Power has now been restored and no further issues are anticipated by the power distributors.

  1. Neil Watson says:

    We have had a further incident of power loss and are again running on back up generator. Sixteen properties remain without power in the area and the expected time for restoration is 21:00hrs.
