I've checked, and the volume of attempts over the past few days seems pretty constant, although there was actually a decrease around Nov 26-29 corresponding to US Thanksgiving holiday.  :-)

I do use denyhosts with ~4000 IPs known to be actively scanning SSH blocked.  I do note an increasing number of malicious scans using "Client: libssh-0.1" string instead of legit connects with "Client: OpenSSH_5.2" or similar....
