I bet that your initial diagnosis is correct: your Internet connection 
at work is going down periodically. You need to try to get to work 
early or on the weekend when the problem is happening, and ideally 
have somebody at home or wherever you're doing the tracert from.

It could also be a DNS problem. When you ping your server, are you 
pinging it by name or by IP address?

Also, do you manage the firewall that your server sits behind? It 
sounds like the firewall may be programmed to block traffic during 
non-work hours.
