Comcast contact for the East Coast

Could someone from Comcast please contact us (netops@citrixonline.com).

Customers behind Comcast on the east coast cannot get to our
216.219.126.0 prefix in Santa Barbara, CA. Comcast's peering with Cox
on ashbbbrj02-ae0.0.r2.as.cox.net may be to blame.

Regards,
Ashe Canvar
Network Engineer

I'm presently hanging off of Comcast in Atlanta (76.17.105.x) and I can
ping traceroute and ping 216.219.126.1

COX has created ticket HD0000015981407 for this issue.

A show route shows us that traffic destined for target IP 216.219.126.0
is going from ASHBBBRJ02 to ASHBBBRJ01, and then directly to the Equinix
Public Peering Switch in Ashburn, and then stopping.

I will be contacting Equinix shortly to continue troubleshooting.

We've been having a similar issue since last Friday; Comcast customers are
unable to get to our 66.59.96.0/24 prefix through Ashburn, Virginia. Could
someone from Comcast also contact us at admin@ctinetworks.com?

Also, anyone happen to know of a publically accessible Comcast looking glass?

Thanks,

Comcast ops folks said they have stated a network change was made last Friday which should have addressed this; are you still having the problem and if so, when the most recent time was they ask?
