Build failures and 500 errors for functions using Edge runtime
A small number of customers who built or deployed functions using Edge runtime between 13:01 and 13:11 UTC experienced elevated rates of build failures due to unexpected error. Some builds succeeded but resulted in 500 errors from functions using Edge runtime. Re-deploy functions using Edge runtime to accelerate remediation.

What to do next

Verify your own services recovered cleanly. Some upstream outages leave queues or caches in a degraded state, run smoke tests before declaring green internally.
Save the post-mortem. Vendors usually publish a detailed RCA 1-3 days later. We'll add it to this page when it appears.

GlobalOutageMap aggregates publicly reported signals. We never claim authoritative status, always cross-check the provider's official channel before making business decisions.
