What to do

• Check whether you use Scaleway Transactional Email. Check your stack

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

• Switch to another region or a fallback provider while it is open, if you have one.

  Otherwise back off retries and queue work, so you don't add load while it recovers.
