Resolved after 57 minutes, on August 7, 2026.
### **Dates:** Friday, August 7th 2026, 11:00 UTC - 13:04 UTC. ### **What happened:** Windows and Intel Mac jobs in `us-west1` failed to start due to virtual machine \(VM\) allocation starvation. ### **Why it happened:** A service crash loop left VMs in an allocated but unclaimed state, while a cleanup bug prevented the system from releasing the orphaned capacity to boot new VMs. ### **How we fixed it:** Restored service stability and cleared stale allocations to resume VM provisioning and clear queued jobs. ### **What we are doing to prevent it from happening again:** Fixing allocator cleanup logic, strengthening deployment health checks, and improving capacity accounting for stale allocations.
