Backend Degradation causing job slowness and caching failures

Jobs across all regions are taking longer to start and cache operations are failing. We are continuing to investigate the root cause.

We have applied a fix and are monitoring its effect. Customers may still see delayed job starts and failing cache operations while recovery completes. We will provide an update within the next 30 minutes.

Our mitigation has taken effect and job start times and cache operations are improving. Customers may still see some delayed job starts and cache failures while recovery completes. We will provide an update within the next 30 minutes.

Caching has recovered, and job queue times across EU regions have recovered. Queue times for larger jobs (16 and 32 vcpu jobs) in US west and US east continue to remain elevated. We are continuing to monitor for any regressions.

This incident is resolved. Job start times and cache operations returned to normal in all regions, and we are continuing to monitor. Jobs that failed during the incident can be re-run.
