I have one hosting customer in Western Canada who regularly sends me email saying that he gets a Gateway Timeout when he tries to point his browser to his site. In fact, if I give him a list of some of my own sites that are on the same server, het gets the same message. Yet at the very same time this is happening, I am able to access the sites. Sites are functional, server is up, everything seems fine. Except that he keeps getting the DNS error...
And if he pings or does a tracert, everything seems OK. But still gets error.
Can someone please take a crack at explaining why/how this happens?
