it is all in the detail

had a p1 case. ha, seems the loadbalancer is getting used to be the blame victim. claim was the loadbalancer probing failed and puts serverfarm out off service. going crazy for few minutes to see what the heck! true web port is open on the server, the probe is a http probe expecting "status 200", hey! "show probe detail" (again it is all in the details!) shows return "status 404". Turns out, newly implemented urlscan rule on the serve was the villain.
