What to do

• Check whether your product depends on Chromatic. 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.

• Confirm your retries, queues and scheduled jobs caught up after the 30m it lasted.

  Anything that failed between 2025-12-15 03:01 UTC and 2025-12-15 03:31 UTC may need a replay.

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

  https://down.guide/feed?provider=chromatic works in Slack (/feed subscribe), Discord feed bots and any RSS reader.
