... except for putting some load on the server?
One of my sites - running D6, perfectly up to date - has been facing some sort of an attack for the last few days.
Logfile has thousands and thousands of requests exactly like this one,
[28/Feb/2014:04:11:39 -0800] "POST / HTTP/1.1" 200 15195 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)"
apparently coming from thousands of different IPs from all over the world.
The site looks normal, I'm the only user (administrator) and total size hasn't changed from the latest backups.
