While jumping on the wagon of poking at a particular 175.x.x.x address, I noticed something in my trace:

10     5 ms     5 ms     5 ms  att-level3-30G.washingtondc.level3.net [4.68.62.30]

Does anyone happen to know where the other end of this tunnel is that magically everything from a DC-DC hop to a DC-LA hop are all exactly 73ms?

thanks,
