Re: Time Warner Routing Issue

Hi Brian,

My school has 2x TW circuits.  Tracing to 68.68.176.1 shows that it doesn't
leave TW's network.  In Chris's previous email, the origion is AS 11351 which
is Road Runner (now owned by TW).  It gets to Albany, NY then dies.

Brian,

wanting to know what other people were seeing with traceroutes and "show
