As predicted there were a few small problems with the site after the move.
The MySQL server setup was dying with too many connections, so that's been tuned. So has Apache and PHP now, so the site should stay up.
Fingers crossed ;)
mod_slashdot
This reminds me of the code that I was telling Hughe about yesterday - mod_slashdot.
A simple Apache 1.3.x module which keeps track of the previous fifty referrers to an Apache server, if more than half of them come from slashdot.org it blocks them.
This means I should still be able to have a .sig linking to my site from there, but a real submission (unlikely) would make my server go offline gracefully.
With a small bit of effort it could be tweaked to keep track of N referrers and drop connections if X% of them came from the same site - that would prevent overload from arbitary sites.
(Of course that would necessitate the changing of the modules name!
