Resolved after 25 minutes, affecting General Services, on May 19, 2026.

resolved May 19, 2026, 10:41 AM UTC

Description: We identified an issue where connections were intermittently failing with the error message: "UNAUTHENTICATED: Token not found". Timeline: The issue began on 2026-05-19 at 08:48 UTC and was resolved on 2026-05-19 at 09:10 UTC. During this period, customers may have experienced intermittent sync failures, with services recovering shortly afterwards. Root Cause: The issue was caused by failures within the scheduling layer due to an internal network disruption. This resulted in cascading failures across dependent connection services. Resolution: The affected connections recovered once network connectivity was restored. All services are currently operating normally.
