Remove Web Application Proxy | Server From Cluster

At 2:17 AM, I drained the traffic. The F5 showed wap-03 's connection count dropping from 1,200 to 0. Beautiful.

And always, always check your health checks. remove web application proxy server from cluster

I ran the stop command: Stop-WebApplicationProxy -Node wap-03 At 2:17 AM, I drained the traffic

But here's the terrifying part. Because wap-03 was "alive" according to basic ICMP pings, the cluster's consensus protocol had been treating it as a voting member. For six months, every time wap-03 choked on a null byte, it would delay the cluster's session replication by 400ms. And always, always check your health checks

But I knew the truth. wap-03 wasn't providing redundancy; it was providing uncertainty . Its TLS cipher suite was outdated (TLS 1.0, a compliance nightmare). Its network card had a known memory leak. And worst of all, the session persistence table would occasionally corrupt, silently dropping 0.5% of payment authorization requests.
