Also, if you call the NOC (network operations center), have them check their DNS to see if there is more than one IP address associated with the name internal to them. Also have them check the ARP cache to make sure that an invalid entry isn't stuck.

Mark do you need anything from me?

Not at this time, David. The problem looks to be very local. It is probably inside the co-lo facility where the server is housed.

Most Data centers will have two pipes or more, for redundancy, say if they're in Texas, having one go to Chicago and the other to LA or NY.... So as possible as it is, because a large amount of people still can get to it, I'd still think to look at the ISP end first. Users should contact their ISP only if having problems because if not, they'll show it as being fine. Now the admins should alert the web host as well to a problem, so they can investigate, but something like this unless you're on the inside isn't as easy to track down.

Basing this off the experience I have with working at an ISP previously and with out the networks my company and it's customers use, which are scattered across the US, and several other countries...having some locations store different servers for Apps and such.

Agreed, more or less. Since the problem is manifesting itself at the 1st upstream router, the problem, statistically, is local to the facility. That is, unless they do physical layer shunting across the US, which is very costly and make little or no sense.

The problem could be a myriad of things from a bad network interface on the server to a HW or SW issue on the upstream device (router or switch) or internal DNS configuration issue or similar.

There is always the possibility that the server is running IP chains or something similar and that the config is screwed up in some way, but that's way far fetched base on what I know.

Like you, I have load of network engineering experience plus telecommunications OS design, work on networking standards committees, and a prior life as a network programmer and college professor. That doesn't mean that either of us knows squat about this problem, however.

This could be the start of a networking banter thread
