(Get the code!)
The existing loadbalancer can detect, and does stop sending requests to hard failed app servers.
Unf it can take up to 60 secs to detect and fail; and
The app servers frequently fail soft: Dead, but still responding to HTTP requests.
Being able to rotate logs without restarting the app servers would solve a similar problem across all of lpnet and edge; where with every rotation, we will fail around 1/4 to 1/5 of all requests until the LB detects the given apps are down.
The edge updates are simply more noticable as all 4 edge servers are updated in a single block. Taking around 15 minutes from start to finish.
