If you're a direct customer, use your MIS contact. We've used them for nearly 8 years, and I've been consistently impressed. If not, your upstream should be your first point of contact. For maintenance (e.g., prefix-list mods) they tend to take their time unless you insist on expedition; but, for performance-impacting issues, they're quite responsive. cheers, brian On Wed, 28 May 2008, Philip L. wrote: :Does anyone have information or a contact at AT&T with regards to :setting up BGP blackholing with them?

Good luck. The problem is the MIS product managers would rather sell you their DoS Clean Pipe solution rather than accept a prefix via a BGP session with a unique community. Their DoS Clean Pipe redirects your impacted networks into their scrubber (Cisco Riverheads) then back towards your network. What I find funny is that on the list of AT&T achievements of the past 100 years, the DoS Clean Pipe is listed in the 2000s while transistor is listed for the 1940s. Whats next for 2008, claiming the Apple iPhone or Cisco Telepresence as an AT&T achievement? Didn't know resetting BGP next-hops was up there next to the transistor. Mr. Wallingford says you should call up your MIS contact, but why should you call up when most other networks let you black hole with an existing or separate BGP session? Sounds like AT&T MIS needs to get with the times and stop catering only to the enterprise T1's. Paul Wall Drive slow...like Brucie.
