They're from Russia, and can keep trying as long as they don't get in.
I had someone from Russia get into one of my boxes once. Someone added an admin user then later on changed the bloody password to admin. of course it was 'brute' forced. The only thing that saved the box was the grsec enabled kernel - PaX kicked in on everyone of the 8 different rootkits they tried. pretty impressive effort I must say.
grsec saved the box even though the attacker had a shell... seems to work better than afs and kerberos i must say ;)
