Closed, ResolvedPublic

Description

@Paladox said this is cp7 depooling but we're getting this multiple times a day. It's clearly unstable. Please investigate.

it's not a cp flapping, it's a problem with mw*. They are causing the healthcheck to hit the timeout thus depool.

The check has been fixed. If the underlying issue still causes issues another task for that should be opened.
