 And here I thought my bandwidth drop in mid-2002 was due to implementing an
                             RSS feed for my site

I did a bit more probing of my webstats [1] and located when my bandwidth
shot up—February 22^nd 2006 [2]:

Table: Bandwidth increase
Date    Bytes   Hits    Status
Okay (200)      Redirects (300) Client errors (400)     Server errors (500)
------------------------------
02-19-06        12,167,334      2,240   2,075   163     2       0
02-20-06        11,955,375      2,017   1,863   151     3       0
02-21-06        12,511,210      2,372   2,197   173     2       0
02-22-06        56,693,839      2,145   1,792   137     13      203
02-23-06        45,939,357      1,737   1,563   152     5       17

I checked the logs on the on the 21^st and 22^nd, and for some odd reason,
Apache didn't bother logging the bytes transferred on the 21^st (and prior)
but did starting on the 22^nd (and afterwards). I switched servers in
February of this year [3] so that's not the explanation—perhaps I upgraded
Apache [4] that month or something (since most of the pages served up on this
domain are done via a CGI (Common Gateway Interface) script, it looked like
Apache didn't bother to track the amount of data served in that case, and
later versions do).

That might also explain the drop in bandwidth around July/August of 2002—I
might have upgraded Apache then and that particular version didn't record the
bytes sent via a script properly. So basically, the bandwidth metric is
useless between July 2002 and February 2006.

Not that I'm overly concerned about it—it was more curiosity than anything
else (and if need be, I could reconstruct the data since I have versions of
previous templates used, but there's no need).

Also contributing to the spike in early 2006 are actual traffic spikes that
happened in April of 2007, like here:

Table: Bandwith Spike
Date    Bytes   Hits    Status
Okay (200)      Redirects (300) Client errors (400)     Server errors (500)
------------------------------
03-31-06        49,231,768      1,977   1,771   196     8       2
04-01-06        148,802,602     5,442   5,233   171     38      0
04-02-06        59,528,160      2,197   2,030   164     2       1

But those are more easily explained as simply more hits.
