- postmortem Feb 20, 2026, 11:03 AM UTC
### **Dates:** Monday, January 5th 2026, 20:40 UTC - 21:04 UTC. ### **What happened:** There was a decrease in Real Device availability in the US-West-1 datacenter. ### **Why it happened:** During a planned traffic flow migration, a network policy applied to the new traffic path was more restrictive than intended and this resulted in a subset of Real Devices \(~40%\) failing to maintain required connectivity. Although the change followed standard change management and peer review processes, the issue was not identified prior to activation. ### **How we fixed it:** The network policy was corrected and affected services recovered. ### **What we are doing to prevent it from happening again:** We are reviewing our network change processes to provide earlier detection of unintended behaviour during planned changes.
