We're aware, Cliffy... for about eight hours now, a spammer has been having a go at the server, bouncing tens of thousands of email
per minute; in addition, someone's forum was under attack as well - these are what we call 'denial of service attacks'; rooting so much traffic through the connections slows down, times out and then locks up the lot.
I just got home from work, and it was still going on when I left, so it looks like they're at least part-way there to stopping this; speaking only personally of course, I believe a round of live executions on the internet might cause some of them to start thinking about what they're doing.
