Progress in virtualization technology, the webserver staff must have configured automatic migration of the server image to a lightly loaded host. This might move a server image to a location that puts it several milliseconds further away from other servers or from its disk storage system. And milliseconds can pile up fast.
It would create huge spike in network availability and thus hard to communicate around the web server to function in such environment. Even deploying better communication system will not ensure best efficiency.
It should be taken care for good algorithm faster access and transport. Technical expertise is important.
