Resolved

cr1.thn was restored to service on the evening of the 28th September and has remained stable since. All services have been closely monitored and have been operating normally.

The cause of the MTU issue that plagued broadband users connected via lns0.vlt after the THN interconnect was lost was identified and we believe is now resolved.

We apologise for the inconvenience caused.

Recovering

All services have now been re-routed in one way or another

Work continues to replace cr1.thn and subsequently to identify the cause of the MTU issue for lns0.vlt so that it can be returned to service, but at this time nobody should have a loss of service - if you are experiencing disruption please email support

There was an MTU issue identified that was affecting broadband users connected via lns0.vlt - we have for the time being withdrawn this LNS from service.

There has been a total loss of the route processor in cr1.thn and a replacement is being organised, and any services that can be re-routed around cr1.thn in the meantime are being re-routed.

Investigating

cr1.thn appears to have vanished without a trace

An engineer is on their way to investigate the rack

This will cause a loss of any services directly connected to cr1.thn, causes a loss of resilience to broadband and other layer2/3 services

Broadband circuits connected via Telehouse North will have suffered disruption followed by a reconnect over the other interconnect.

Apologies for the inconvenience caused - more as we have it
