Between August 24 at 23:38 UTC and August 25 at 00:08 UTC, a subset of customers using Inngest Connect experienced delayed and failed function runs due to an internal networking issue that disrupted connectivity between Connect services. We reverted the change and restored service. Although Connect buffers worker responses, stalled internal API calls delayed acknowledgements and subsequent replies. In some cases, request forwarding failed even after a buffered response had been received. We fixed the root cause, improved Connect’s failure handling, and enhanced our internal observability so we can detect and respond more quickly to similar problems in the future. Affected customers should review failed Connect runs during the incident window and replay them after confirming that doing so is safe and idempotent.
