Intermittent API Errors

What to do

• Check whether you use Mailgun API, Control Panel, Email Validation, SMTP. Check your stack

  Drop a package.json, lockfile, Terraform or a list of domains at down.guide to see every provider you depend on.

• Confirm your retries, queues and scheduled jobs caught up after the 3h 40m it lasted.

  Anything that failed between 2025-05-14 18:38 UTC and 2025-05-14 22:18 UTC may need a replay.
