Not seen anything specific on the zen pages so here is some handy info from another source. This looks like it's going to be a big one and may cause problems.
BT Wholesale 21CN broadband WBMC shared platform is undergoing a Programme of works which started in May 2010 and is expected to be completed in March 2011. This will increase WBMC shared capacity and resilience for the ongoing heavy bandwidth demand.
As part of the expansion Programme a schedule of works has been planned and there is a need to upgrade the infrastructure at the interconnect node at Stepney Green. Upgrades have already successfully been carried out at interconnect nodes in Birmingham, Colindale and Manchester.
Work is now planned during November at Stepney to increase capacity and resilience which will allow for more edge routers to be connected to the network. This planned work will result in an outage of up to 6 hours, to minimize the impact on our customers the work will be carried out between Midnight to 6AM
The Target dates for the planned works are 23rd November for Stepney Green.
The Planned work will have the following impact:
At the Interconnect site (Stepney Green)
* All End Users who are connected to the Faraday backhaul WES/EAD circuits (Host link) will have their service terminated and reconnected on to the BRAS when the PEW begins.
* All End Users who are routed through the Faraday BRAS will have their service terminated when the PEW begins irrespective of what interconnect node they are connected to.
At the other Interconnect sites (Faraday, Manchester, Birmingham and Colindale)
* All WBMC shared End Users will be unable to authenticate after midnight at any of the 5 nodes. Any new authentication requests made after midnight will be terminated on the BRAS and End Users will not have access to their service provider.
* All new authentication requests on WBMC Shared made after midnight will lose service on all interconnect nodes. This means they will not be able to connect to their CP irrespective of what Backhaul (host) link they connect to for the duration of the PEW.
* Service will be maintained if the End Users do not log out before midnight. This means that any End User that is logged in before the work begins will retain the connection provided he does not log out during the PEW.
