I'm not sure that going back that far is going to offer anything
conclusive, as it could have been any number of scanners looking for
vulnerabilities.  Looking at my logs back to the 19th, I have isolated hits
on the 19th and 23rd.  However, they really started to come in force at
22:29:39 MDT, two seconds after Clayton's.  My first attempt came from an
IP owned by Level 3 Comm.
