(Posted by Alexis Rosen) Sat, Jan 25 2003 -- 7:45 AM --------------------------------------------------------------------------- Many Panix services were disabled on-and-off (mostly off) from about 12:30AM saturday morning up until recently. This was the result of a massive DDOS (distributed denial-of-service) attack that apparently affected a number of ISPs. We don't know a lot about this yet, though we've been working on it all night, since the volume was far more massive than any attack in our previous experience, and apparently triggered at least two separate bugs in Cisco's IOS (memory leakage and HSRP failures).
The attack is continuing, on and off. We've taken certain measures, which are partially effective, but we're uncertain as to how they'll stand up.
Mail and news are not being lost, but they are delayed when the various servers become inaccessible.
I'll post another MOTD if and when I learn anything else interesting.
