What to do

• Check whether you use Shippo USPS. Check your stack

  Paste a package.json, lockfile, Terraform or a list of domains at down.guide/stack 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.

• Watch Shippo's own updates; this page re-reads them every minute.

• Subscribe to Shippo's feed to hear about the next one first. RSS feed
