httpd access logs are inaccurate, unless you are using mod_logio or
similar; they'll show a complete download amount for partial downloads,
which causes AWstats and Webalizer to become *massively* inaccurate.

We had a situation with mirror.bytemark.co.uk a couple of months ago
where someone was grabbing the first 1.5MB of a DVD ISO to test
connectivity over their wireless mesh networks, over the course of 2-3
months it looked to Webalizer like they'd transferred >10TB.

Reality:  bandwidth graphs of the switchport do not correlate,
contacting them was fruitful, default access_log has serious flaws.
