UPDATE 22:25 UTC: Google appears to have fixed it. Cold starts are working again (seen i n us-central1) even for functions still on automatic updates. The on-deploy redeploy below is still a valid fallback if it comes back. Outage window seen: about 21:15 to 22:25 UTC.

FIX (confirmed by several people, works immediately): redeploy with the runtime pinned instead of auto-updated. * Cloud Functions gen2: gcloud functions deploy FUNCTION_NAME --gen2 --region REGION --runtime-update-policy=on-deploy --source PATH_TO_BUILT_FUNCTIONS (keeps triggers, secrets and settings)* Cloud Run source deploys: redeploy with --no-automatic-updates * A plain redeploy does not help: it keeps automatic updates on and lands on the same broken runtime.

Script it if you have a lot of functions; it's one deploy per function.…
