Hi All,

Not sure where the problem is at but several packets are being dropped
to several different hosts from the DC area. (This is not the Google
DNS problem)
I tried connecting to several different known sites with roughly 40%
being unresponsive from two seperate ISPs (Speakeasy and Comcast.)

Traceroute to sans.org via Comcast:

~~~~~~~~~~~~~~~~~~~~~~~
Traceroute via Speakeasy would timeout.

Same thing goes for other sites
ubuntulinux.org
www.osvdb.org  for example.

Anyone else having similar problems?
