Many sites block ping wholesale. Rather than ping, why not use a GET or HEAD request to see if a server is up or not? It's heavier-weight than a ping, to be sure, but since the thing being tested for is whether the keyserver is up or not, a HTTP request will give you a much more useful answer than ping which can only tell you if the box is powered on and has an IP address.
