What was the result of ntop? protocol breakdowns, top IP SRC/DST etc.
Does syslog point you to anything suspicious?
chkrootkit ?
What do you use to audit your Apache logs? Does that show up anything
interesting (hosting a large file for download maybe).
Without physical access, it's hard to trust the output of tools you
install.

Jonathan,
I'd be curious to get a copy of the list of networks that you're
seeing this
traffic from. I work for a large managed security service provider
and I
could cross reference these networks against data that we're seeing
from our
corporate customers.

All,
I have a leased server I use to host some websites and for the past
week I have been getting traffic warnings. The server has been
transferring > 1GB of data per day, which is unusually high,
especially since I moved my mail to Google Apps. I have noticed a
ridiculous amount of attempted proxying attemptes in my logs, but
I do
not have mod proxy turned on. I suspect my server is on some
list. I
firewalled off a large number of subnets from China and my traffic
dropped for a few days, then this morning, 2735MB transferred in 24
hrs.
As of right now, I am planning to blackhole all China traffic, since
thats where most of this is comming from, along with the occasional
traffic from France and other places in Eur. Is this common? If so
are there any other remedies?
