We currently have an ongoing attack, and cannot get
a directly adjacent network to respond.
(Participate in a traceback)
The list at puck.nether.net has a few errors....
Jared: The following phone number is disconnected:
Concentric Network Corp.
internex.net, concentric.net, concentric.com
2828
+1 408 327 2470
Cool! I love it when we find these things out from
external sources. 
I'll put a bee in the bonnet of the folks at work to
track this down and get it operational again.
noc@internex.net
The phone number appears to be no longer operational.
The email gets an auto-responder.
We have not received a human response to an "urgent" in over
24 hours.
:(
If you are a peer of ours, please send correspondance to
"peering@concentric.net" -- that actually hits the clueful
people. If for some reason that address gives errors, send
it to "peering@internex.net". That second address isn't
supposed to exist anymore, of course, but it's always good
to have a second channel in case the primary fails. 
We have an ongoing attack that has been running for over 48
hours total so far.......
Would someone with Concentrics (IP Clueful) Security
please contact me!
(And while you are at it, please update puck's NOC contact
list)
How does one do that...I see a form for adding a new entry,
but I don't see a form for updating an existing entry.
You appear to have a script kiddie pointing smurf at a
downstream.
Please send as much of the relevant information on the attack
as you can to peering@concentric.net, and we will work with
you on tracking it down. Please include which peering location
you are seeing the traffic from, and destination IPs that are
being hit.
Thanks!

You're welcome--sorry it had to come to a public forum like this.
