[nsp-sec] Spambots patch Tuesday?

[Zoe O'Connell]

We saw a significant drop from 50 rejects/s down to 10 rejects/s between
1100 and 1200 BST and back up to normal levels again now - but no
reduction in overall internet traffic, so it certainly looks like
something happened that took out just spam senders for an hour.

Could be related to the fact Intercage have moved provider to AS27595,
as reported by Steve Shelton just now? (I'd be surprised if Intercage
could be traced back to as much as 80% of the spam we get, however)
