Anyway, back to being on topic, I don't think HE.net offers many additional services, other than IPs for instance, and power, as it's more of the just "colo and bandwidth" provider, no reboot switches or anything of that sort.
A simple visit to their site revealed these "additional services" :
* Content distribution
* Load balancing
* Raw newsfeeds
Some of their specials disallow you from even adding additional power from what I hear, but overall, HE is a good provider, so whatever they are doing, it must be right..
