Twilio will conduct planned infrastructure maintenance on the London (IE1) PoP from August 21, 2026, at 14:00 PDT until August 21, 2026, at 21:00 PDT. Overall service impact is expected to be minimal; however, Voice traffic routing through the IE1/London edge location may experience a brief interruption or intermittent impact of up to 90 seconds during traffic reconvergence.
Customers with redundant connections established across other PoPs are advised to manually redirect their traffic prior to the window to ensure seamless failover. Non-redundant connections routing directly through the affected infrastructure will experience a brief service drop during the switch replacement.
