Happo incident

Happo.io temporarily down

Resolved on April 18, 2026.

resolved Apr 18, 2026, 11:26 AM UTC

While applying an infrastructure change to our cluster, our load balancer was misconfigured and ended up in a state where it sent HTTP traffic to the wrong nodes. The issue was discovered right away but it took a while to figure out the root cause (load balancer config). External traffic was briefly affected with API requests to happo.io timing out. The issue has since been resolved and all services are back up and running.
