We've already done this for a number of sites in this range, and I've
been meaning to make such things public on our weblog as an article
about "resource planning" and a transparent discussion of what things
really cost (it's related to the tendency of web hosts to oversell
resources and how I think podcasting is the end of that practice).
It's been primarily in the wake of what we did when a number of
podcasts here found themselves on page one of iTunes, and we watched
with them as they cranked out a terabyte of bandwidth (which we
didn't send them a bill for, a benefit of underselling bandwidth).
It's a helpful discussion in general, because a common "goal" is to
be "popular" and if I would use up all my fingers and toes if I
counted the number of people who showed up at TextDrive on a $132/
year account, had one of these "political weblogs", then got picked
up by a "MSNBC" and then ... we're surprised to find out that such
popularity requires a system administrator and about $50,000 of
hardware (that's already nicely discounted as part of our deal with
Then bandwidth ... the reality is this, when we co-lo in a "bandwidth
competitive" environment like Equinix, then you can get down to about
$15/Mbps/month from a single provider on a 100Mbps unmetered commit.
This is what an "alternative" provider like Hurricane Electric is
going down to and it's not the kind of rate that's just available to
anyone, it's part of a larger co-location setup.
100 Mbps is 16,000GB/mo, or roughly 800 accounts x 200GB/mo
What's 200GB/mo? It's 1000 downloads a week of a 50MB (a standard
stereo mp3 of about 40 minutes) podcast.
