Re: Urrr... A-root server foul ?

I think the last line of my traceroute is instructive:

traceroute 198.41.0.4
traceroute to 198.41.0.4 (198.41.0.4), 30 hops max, 40 byte packets
 1  cr1-hfc2.vista1.sdca.home.net (24.0.178.1)  17.192 ms  21.047 ms  18.722 ms
 2  10.0.219.1 (10.0.219.1)  9.061 ms  16.608 ms  5.648 ms
...
15  a.root-servers.net (198.41.0.4)  104.697 ms bip1.internic.net (198.41.0.24)  151.400 ms  100.606 ms

198.41.0.4, 198.41.0.24 can you say whoops! I knew you could...

sigh.
