Nice idea

Seeing as we now have 6GB this is unlikely to be a problem again, though.
You could try asking Bjorn to set up a .htacess script that automatically forwards people to this address once the server hits its bandwidth limit. I'm not quite sure how you do it, but I think it's possible

intersting idea.
I'll ask him.
And the 6gb limit is reachable IF the problem is malicious activity behind the scenes.
Such as someone having a script that is using the bandwidth constantly.
I had that problem once on a client's server.
it took forever for me to find the malicious script (among about 20 million scripts it took 6 months to track down the damn thing)
