Well, that's interesting.  Average traffic since just after midnight (MDT) on 
April 2nd has been 268.9 MBytes/day.  Thursday the 5th has been the busiest day 
so far, with over 7,200 HTTP requests representing 1,730 HTML pages.  Just 
under half of all the traffic has been going to (are you ready?) Poland 
(approx. 49.30f all traffic, measured in bytes).  Only two distinct addresses 
in Poland accounted for all this.

Another 29% approx. has been to unresolved numerical addresses.  The remainder 
of traffic's spread around pretty evenly.

In 3.5 days, 1.2 Gigabytes of traffic has occurred, with 820f that being PDF 
downloads!  In summary, except for a couple of data gluttons, usage appears to 
be reasonable.  I'll keep an eye on it -- if it gets too bad, I'll throttle it, 
or lock out IP addresses that are abusing the site.  (Only a temporary fix, to 
be sure...).

For the moment, it's not a big deal (although I got a phone call from one of my 
partners this P.M., asking me to attend a meeting during which we'd be 
discussing some problems with our server farm.  "Oh-oh," I thought.  Turns out 
it was an unrelated issue...).

Anyways, replicating on several mirrors would certainly help...
