Email notifications for SLOs, Triggers, and Anomaly Detection not sending

What to do

• Check whether you use Honeycomb ui.honeycomb.io - US1 Trigger & SLO Alerting, ui.eu1.honeycomb.io - EU1 Trigger & SLO Alerting. 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 1h 1m it lasted.

  Anything that failed between 2026-10-22 16:06 UTC and 2026-10-22 17:07 UTC may need a replay.

   Between 03:53 PM UTC to 4:08 PM UTC we saw email send failures elevate in which a small number of customers (10 enterprise, 8 self-serve, and 1 pro plan) were impacted. This came to 508 emails in total, or ~1% of our daily email send. We are working to ensure this failure mode is not able to happen again.
