I dunno if you guys know how much it sucks to have been working a Dial up Network Operations Center when that hit. We are running MAX ASCEND TNT Access Servers.. anyways they usually take about 552 calls, and route then to the internet at their dial up speed. We have 52 of these. SO thats like, 28,704 users online that i manage. NOT including the outsourced POPs.

SO imagine, when 28,704 dial up users start scanning at a flood like rate. A DS3 is plugged into each Access Server to provide bandwidth for the users... apparently... 552 users scanning at once is far more than 40 MBPS. (DS3 cap)

Needless to say, it was like a dos attack on our access servers. It was a nightmare for like 3 hour dial up downtime, till we found a filter that stopped the scanners packets.

ah memories...
