You are not alone - we observed the same here. See also:

We monitor and block attempts to brute-force SSH logins.
Usually we block a few a day, with at most about 60.

Over the weekend we had a spike of over 500. I.e. 500 separate source
addresses trying to login to multiple accounts/machines using 1000
different IDs.

Anyone else seen this, or is it just us ?

(BTW, my previous collection of attempted ID/passwords - from a hacked
sshd - is at http://andrew.triumf.ca/ssh_pass_file2.html )
