Issues sending email and Slack notifications

What to do

• Check whether you use Lattice Lattice Application. 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 2m it lasted.

  Anything that failed between 2026-08-18 21:32 UTC and 2026-08-18 21:33 UTC may need a replay.

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

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