Weird SSH attack last night and this morning (still ongoing)

I don't know what is going on last night and this morning ... I have three Linux servers facing the Internet, two on cable modems and another on a static IP/commercial connection and this last one is a gateway to a Web/FTP/SMTP/Pop3/NTP Linux based system.

I have DenyHosts installed on all three and have blocked about 75 attempts .. from known compromised adresses .. The log shows (obviously) that there where even more attempts from adresses that are unknown to DenyHosts but there was only one login attemps per adress and it was with the Root account .. which is obviously blocked in my sshd config ..

Of the three machines, one of them only had about 10 attempts, but the other two had about 200 attempts .. all of them with only 1 try with the user Root ..

Is any one else seing this? or am I being targeted? This is still going on now .. and it started arround 10:00 last night GMT+4
