It's interesting to see the small "explosion" of users in 2 years from 2001 to 2003, but I think the monthly new users now must be well over that.

I think I first came across this site looking for stuff related to C.E.R.T. and in the days that Google actually gave you exactly what you were looking for, this was near the top.

When was the big server meltdown? I don't recall that.
