So, it was a TCP port 80 attack directed against one IP address.
I passed this on to my contacts at CAIDA who passed it onto the UCSD NOC who have got the
IP blocked.
The traffic has now returned to normal.

Marius,
If you filter it upstream (meaning filter it at the transit border level) it would not
saturate the public interface anymore as it would not reach the transit pipe anymore.

And how would that help?
It won't make the bandwidth available, the packets would still saturate the public
interface.

FYI
The gateway machine at UCSD has been under a sustained DDOS attack now for over 24 hours,
so if anyone is seeing heavy packet loss through the gateway, that’s why. The 1Gb/s
interface is max’d out. You can view the interface stats here:

Seems to be a DNS DDoS.
Can’t you filter upstream? Let me know if you need assistance.
