Yes, its an ASP actually. Unfortunately, there isn't much to write home
about (or at least not much "new" to say to anybody that runs a network
of this scale).

Essentially all the configuration is kept in SQL databases and ton of
scripts manage the virual server creation, mailscanner configuration,
software update services, statistics, blacklists, whitelists, usernames,
passwords, you name it. Scripts are used to create vserver images
(http://www.linux-vserver.org) which are then pushed to previously
mentioned pre-built linux servers. Images are started and from there the
scripts inside the vserver keep the context configuration in sync with
the db which is managed directly by the user through the control panel.
They also report back on the load, status codes, hardware issues, etc.

Its your basic enterprise network loosely held together by a number of
perl and shell scripts :)
