MT1 cluster - increased latency and webhook delivery failures

What to do

• Check whether you use Pusher Channels Webhooks. 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 4h 46m it lasted.

  Anything that failed between 2025-10-20 08:10 UTC and 2025-10-20 12:57 UTC may need a replay.
