Hello,
I am seeing a really weird routing issue. I have customers who are having trouble connecting to hosts on the internet. The common item seems to be Savvis.
orange:~>traceroute mail.tecumsehherald.com
traceroute to mail.tecumsehherald.com (64.14.74.42)
1 204.16.245.97 (204.16.245.97) 0.580 ms 0.800 ms 1.020 ms
2 204.16.241.225 (204.16.241.225) 0.496 ms 0.478 ms 0.699 ms
3 64.209.102.233 (64.209.102.233) 7.177 ms 7.420 ms 7.417 ms
4 te1-3-10g.ar2.DCA3.gblx.net (67.17.108.145) 7.630 ms 7.870 ms 8.105 ms

6 * * *
Hop 5 is a Savvis router.
Now if i go to Global Crossings looking glass and run a trace from their DC router to the same host, it makes it.

Now to top it all of, if i run a trace to the 64.14.74.41, instead of 64.14.74.42 it works...
