[sudo-access] help! network is down at Omni!

the front door computer is unreachable, because some network switch between it and the server is not working right i guess... either one of the switches upstairs (in the "public computer lab") or something in the network cage. I had to leave before i was able to figure out what was wrong and I can't access the front door computer from theh network, so I don't know whether card access will work although now that i think about it, it probably does work. the wifi was being really really really slow tonight (thursday night) and Arthur and I were trying to figure out what was wrong, and Yar and Marc helped remotely, but we never figured out where the problem was, and I didn't realize until i had to leave that the front door computer is entirely inaccessible. $ ping 100.64.64.11 "No route to host" even though i power cycled it and it's getting a link light. I don't actually know where the other end of its ethernet cable is but since the front door computer is important to security and accessibility, this worries me. Can someone who understands the building's network please try to fix this ASAP? -jake
