The problem is twofold: 1. Many large sites haven't installed 1.8b yet and thus do not contribute to the spam detection. It is typical for large LISTSERV sites to test things more carefully because the impact in case of screwup is bigger, so we'll just have to wait on that one. 2. The core is overloaded and this prevents alerts from being propagated at a decent speed. One of the core site spends 5 1/2 hours a day offline on the average! Luckily, the detection is done in parallel, so in principle each region should be able to detect the spam on its own. However there may be regions where there aren't enough non-core 1.8b servers (or enough targeted lists on such servers) to detect the spam. For instance in Europe we didn't catch the Ukraine spam because for some reason it was only sent to the LINKFAIL/NODMGT-L et al lists that are peered at DEARN (1.8a), and then to GUMNCC. It wasn't sent to any list at SEARN, HEARN, and so on, so there weren't enough events in Europe to call it a spam. From LISTSERV's perspective it could just as well have been minutes posted to 3-4 Terena lists :-) Once the core migrates to 1.8b and something is done about the INTERBIT disaster, things should work a lot better.
