Hi all!
Trackbacks are back in business. Some of them were lost during the attack, either rejected immediately or logged and then overwritten, but we do have about 50,000 that made it through and were waiting to be processed.
And that's after the stage 1 and 2 trackback-blocking methods (1 is changing the name of the trackback script; 2 is blocking the worst of the bastards either in the firewall or in Apache, before the trackback is even recorded). All told, the number of trackbacks arriving at munu is something like 100,000 per day.
Yuck.
Anyway, of the 50,000 that made it through, 49500 were rejected by Snark, leaving 500 to actually update the blogs. Normally Snark rejects about 99.8%, but since 80% of the trackbacks now don't even make it to Snark, that's probably about right.
One minor hitch - I lost the latest copy of the Snark blacklist, and had to go to an old backup. Since Snark builds its blacklist on the fly based on Snarkian probabilities, that's probably not too much of a problem. If someone sent us 200,000 trackbacks before but got lost along with the blacklist, they will very quickly and automatically find themselves back on it if they try that again. (And the worst thing they can do is try to get lots of trackbacks through very fast. Anyone who sends more than 5 trackbacks in a minute gets blacklisted temporarily; send 50 in 10 minutes and Snark makes it permanent.)
Snark is currently crunching away updating blogs with the new trackbacks... Which takes forever. The sooner we move to Minx, the better.
