Resolved after 3 hours 12 minutes, affecting Function execution, on July 16, 2026.
Throughput and latency have recovered and the system should be fully operational again. The core issue is related to the part of the system that persists run state. Some operations experienced and increase in errors and retries, causing a backlog in some parts of the system and some failed operations like checkpoints or signals. We are continuing a thorough post-mortem investigation to prevent reoccurrance.
