This happens when one of the haproxy servers is down from that haproxy instance (one of the hosts haproxy redirects too, not to be confused with the haproxy server itself).

The procedures in this runbook require admin permissions to complete.

Error / Incident

In the alert you should see the instance (the haproxy host), the backend (the web service being proxied) and the server (the server the requests are proxied to). That might get you started on where to look.

Debugging
