Brief failures on inbound calling

Incident Report for Simwood

Resolved

It appears that a routine upgrade to our call routing engine disrupted some incoming calls this evening from 20:25 to 20:57. This type of update is quite normal for us and happens very often as part of our continuous development and deployment. It was being progressively rolled around the network such that calls could failover to the previous version in the event of any failure. However it did not fail and whilst passing all unit tests appears to have caused unexpected call rejections for calls hitting it. The deployment was paused as soon as we were aware of issues and has been rolled back. We will investigate the underlying issue and resolve before resuming continuous deployments. Apologies for anyone affected.
