There's nothing in the data here that explains the problem. It doesn't *look* like a network issue. Have you tried using a different computer at work to see if it's related to your computer specifically? Another possibility is that there's a proxy server (or some similar network item) at work that's causing problems.

This would be a great question to pose to your network people at work (or, if you don't have a network person at work, the person or company who configured the network originally). If you are that person, or if there is no apparent local reason for the problem, then contacting Roadrunner would be the next step I'd take.

Good luck!
