Subject: Service disruption on 18 August — summary and actions
On Monday 18 August between 11:50 and 12:40 BST, calls failed or connected slowly due to a software defect that caused excessive resource consumption on infrastructure supporting our call-routing platform. During recovery, a clustered database entered a protective state that extended the disruption. Service was fully restored by 13:00 BST; no data was lost.
The defect was identified and fixed the same day. We have added hard resource limits that make this class of issue impossible to recur, hardened services to ride through transient infrastructure faults, and improved our monitoring to catch abnormal growth much earlier.
We apologise for the disruption caused. If you observed impact beyond this window, please contact your local support.
Kind Regards
