    ### **Dates:** Thursday, October 9th 2025, 10:28 UTC - Tuesday, November 11th 2025, 11:34 UTC. ### **What happened:** Virtual Android testing availability gradually decreased in the US-West-1 data center, this led to increased error rates in starting sessions, The error rates remained high between November 4th and November 11th. ### **Why it happened:** An increased and sustained load on our service led to reduced availability of Android virtual VMs, increasing wait times to start sessions, which in turn led to an elevated number of failed sessions. ### **How we fixed it:** This was resolved by increasing infrastructure capacity and optimizing resource utilization. ### **What we are doing to prevent it from happening again:** We have improved monitoring & alerting, enhanced post-deployment validation and improved capacity planning.
