RE: Problems with either Cisco.com or AT&T?
Yep; when I sent my previous note, AS109 was still originating routes. But packets seemed to die at the border router. Now I'm also seeing routes via AS701 (UU/Verizon Biz) and AS1239 (Sprint) as well as AT&T, but still no connectivity. A few moments ago I was getting a response from the www.cisco.com website, but it was a 403 Forbidden response. Thus I suspect that it's not even a network problem so much as a website (LB, server, etc) issue, or a DDoS attack, etc. (Perhaps operators are changing route policy, trying to "fix" the wrong issue?) -Benson > -----Original Message----- > From: Michael Airhart [mailto:mairhart@xxxxxxxxx] > Sent: Wednesday, August 08, 2007 3:06 PM > To: Schliesser, Benson > Cc: nanog@xxxxxxxxx > Subject: RE: Problems with either Cisco.com or AT&T? > > I can't speak for Cisco or Cisco IT, but as evidenced by this email, > at least part of our connectivity is up. > > No doubt someone official is looking at it as we speak.
