Update - Connectivity to Swindon and Gloucester has remained stable since last night with no further interruptions.
The network in these two locations remains 'at-risk' whilst the backhaul has been re-routed.
We are expecting further updates later today from the carrier on the root cause, as well as the steps to restore full resilient backhaul (the connectivity which links these exchanges back to our core network).
We do intend to publish a reason for outage on this status page once we receive this from the carrier. This may not be released for a few days.
May 23, 11:25 BST
Monitoring - Shortly before 21:00, connectivity was restored to our Gloucester exchange, followed at 21:38 with our Swindon Exchange.
All services will have restored following this, with the last remaining Gloucester services being restored shortly after 22:00.
Should any customer in Swindon or Gloucester continue to experience an interruption, please reboot your router. If following this there is still a problem, please contact us for further investigations.
Services from the Swindon and Gloucester exchanges are considered 'at-risk', as our carrier's network engineering team has re-routed the circuits via an alternative path.
We await the carrier's reason for outage, however initial indications suggest multiple failures within their network preventing the automated failover as designed.
At this time, all services in Swindon and Gloucester remain 'at-risk' given the re-routing.
An emergency change window shall be organised in the coming days to restore the protected backhaul service once our carrier has fully investigated the problem.
We apologise for the extended interruption today.
