Scheduled - We are undertaking scheduled maintenance to perform an essential upgrade to one of our Slough SS7 switches on Thursday 12th September.

Calls will be rerouted during this time and we do not anticipate any impact to service, although there will be a reduction in inbound capacity during this work as some links are taken out of service, for this reason the works have been scheduled out of hours when traffic levels are lower.

This is one of multiple upgrades taking place which have been staggered to ensure minimum disruption in the event of any complications.

Resolved - We believe this is now resolved and apologise to anyone affected.

Please remember to use DNS in accordance with our interop guidance and to enable speedier resolution of issues like this. We still saw more traffic hitting London than other availability zones even after swinging it away in DNS, suggesting many are not.

Thanks also to those in our community slack for the realtime feedback.
Sep 10, 11:23 UTC
Monitoring - The DNS change at 11am BST (10 UTC) rectified this for all customers using out.simwood.com rather than forcing traffic to London. New nodes have since been deployed in London and are now carrying most traffic. Former nodes are being drained down and will be destroyed once clear.
Sep 10, 10:47 UTC
Identified - Some of the nodes in our London availability zone are showing elevated load. DNS has already been changed to Slough and we're in the process of adding new nodes to London in order to cycle the existing out.
Sep 10, 10:20 UTC
Investigating - Whilst aggregate volumes look normal, some customers have reported high PDD or timeouts on certain calls. We're investigating.

Scheduled - We will be performing maintenance on network infrastructure terminating in Telehouse East in the above window.

Whilst we anticipate no interruption to customer traffic, we will be proactively moving voice traffic away from our London availability zone as a precaution.
