[lug] Connection problems from Europe

[Jeff Schroeder]

Carl asked:

> Can you do a traceroute to your host from Europe?

Good idea.

To get to the IP that "works", traceroute takes 22 hops (full messy 
output shown below).

In attempting to get to the IP that doesn't work, traceroute dies after 
15 hops.  It fails at a wcg.net address:

15  chcgil1wcx3-oc48.wcg.net (64.200.240.37)  122.041 ms  114.478 ms  
113.566 ms

That's certainly interesting.  I don't know where wcg.net is; a couple 
of quick Google searches for geolocation engines turned up "unknown 
location".  But it indicates to me that the connections aren't making 
it into Boulder at all...

Hmm...
