We are seeing a problem with BT 21CN ADSL and FTTC circuits being unable to log in since approximately 18:00 today. Existing sessions are working fine but are failing to reconnect when they drop. 20CN ADSL and TalkTalk backhaul circuits are working fine. BT have raised incident IMT25152/14 which looks to be related, but just says they are investigating a problem.
BT have reported that service should have been restored as of 20:10 this evening. Customers who are still having problems should attempt to re-connect as they may be stuck on a BT holding session. Anyone still having problems after doing that should contact tech support.
