Timeline of updates
- resolved
This incident has been resolved. Some deployments created between May 18, 2026, 06:15 PM - 10:16 PM UTC may have experienced increased ERR_MODULE_NOT_FOUND function invocation errors due to a bad rollout. Deployments created outside of this window are unaffected. The fix is being rolled out to existing deployments retrospectively and is expected to finish in the next few hours.
