As part of an on-going programme to upgrade the 21C Network, between February and July to cater for increasing capacity, BT will be replacing Broadband Aggregator switches with bigger, higher capacity switches. This message is to inform you that on the 16th May from 22:00 to 06:00 and on the 17th of May 2012 BT Operate will be upgrading the (Glasgow) WBC/WBMC aggregation node. They are upgrading the hardware of the BEA (Broadband Ethernet Aggregator) which aggregates all the 21CN WBC/WBMC BRAS’s in Glasgow. There will be a loss of resilience from 22:00 on the 16th to 00:01 on the 17th followed by a total outage of 21CN WBC/WBMC broadband End Users connected to Glasgow BRAS for 1 hour between 00:01 to 02:30. The service will be back with a loss of resilience in this time frame. Full resilience will be restored between 03:30 and 06:00. There will be another short outage of 10 minutes between 03:30 and 06:00 while they test the switch-over function within the BEA.

BT advise that it is extremely important this upgrade proceeds as part of plans to ensure sufficient capacity for the Olympic Games and apologise for the late notification.

Serious BT Incident Raised 3rd April 2012 13:53

Summary: BT are currently experiencing a Serious Incident to their network impacting broadband service across all providers in the Scotland (Edinburgh, Glasgow, Carluke & Dunfermline) area. As a result CPs may be experiencing a loss of service. They are investigating the incident and aim to restore service as a matter of urgency.

Next Steps: Support teams are now working to understand the full impact of this incident and the measures to be put in place to restore service.

Further updates will be made as information becomes available.

We are aware that there are currently problems with one our racks in Telehouse East due to a possible power issue. We have engineers investigating and are already in communication with Telehouse Operations to rectify the problem as quickly as possible. As soon as we have more information we will update.

We are currently experiencing problems with stoke.core.enta.net, affecting directly connected leased line customers. Traffic which would normally pass through stoke.core.enta.net is currently passing across alternative paths.

Engineers are currently investigating the cause of the incident and more information will be provided when it becomes available.

Thursday 29th March 2012, 00:00hrs – 06:00hrs

During the above maintenance window, work will be conducted on the power infrastructure within our Interxion point of presence. This work will be disruptive, so affected colocation customers will be contacted directly and advised of their individual expected downtime.

Tuesday 27th March 2012, 00:00hrs – 06:00hrs
Wednesday 28th March 2012, 00:00hrs – 06:00hrs

During the above windows we will be moving all connections on telehouse-east2.core.enta.net to a new router, individual connections will be moved 1 at a time and will take up to 10 minutes each. Once the work has been completed the new router will be named telehouse-east2.core.enta.net.

This work should only affect customers that are directly connected to this equipment. Users of our standard non-L2TP DSL service should not notice the impact of this change. Any L2TP customers that have an interconnect into this router will either route via their alternative interconnect where available, or will lose service as described above.

Wednesday 8th Febuary 2012, 00:00hrs – 06:00hrs

We will be replacing blades in the following routers:-

• interxion.core.enta.net
• telehouse-east.core.enta.net
• telehouse-east2.core.enta.net
• telehouse-north0.core.enta.net

There will be several short (up to approximately 20 minute) outages during this time affecting all customers directly connected to the above routers.

Some routing instability is also expected as traffic is routed over alternative paths.

Tuesday 24th January 2012, 00:00hrs – 06:00hrs

During this maintenance window, additional PWAN infrastructure is being added into our Global Switch POP in London. We are also taking the opportunity to upgrade the IOS on core PWAN routers. There may be several short (up to approximately 15 minutes) outages during this time affecting all PWAN customers.

It should be noted that this maintenance will only affect PWAN customers.

There has been a power failure at our POP in Stoke. The UPS batteries are now exhausted and we have lost contact with the router. We do not have an ETR at the moment.

As previously advised to partners, we have today entered our Network Freeze period in order to protect the quality of your services over the Christmas period. This means that until 03rd January 2012 no installations or other non-essential activity will be conducted. Please note however that there still may be the need for emergency activity, however this will be advised as appropriate. May we take this opportunity to wish our customers and partners a Merry Christmas and a Happy New Year.
