Since its introduction in 2003, the network has consisted of
"supernodes" made up of regular users who had sufficient bandwidth,
processing power, and other system requirements to qualify. These
supernodes then transferred data with other supernodes in a peer-to-
peer fashion. At any given time, there were typically a little more
than 48,000 clients that operated this way.
Kortchinsky's analysis, which has not yet been confirmed by Microsoft,
shows that Skype is now being powered by a little more than 10,000
supernodes that are all hosted by the company. It's currently not
possible for regular users to be promoted to supernode status. What's
more, the boxes are running a version of Linux using grsecurity, a
collection of patches and configurations designed to make servers more
resistant to attacks. In addition to hardening them to hacks, the
Microsoft-hosted boxes are able to accommodate significantly more
users. Supernodes under the old system typically handled about 800 end
users, Kortchinsky said, whereas the newer ones host about 4,100 users
and have a theoretical limit of as many as 100,000 users.

Gee, I wonder why they didn't use Windows servers? Could it be that
Linux was easier/more efficient/more secure? Maybe they should pass
the info on to their troll department, give DFS and Flatfish a
briefing.
The fact they are using Linux seems to be a deep company secret. It
was discovered by someone on the outside. In an official statement,
the company referred to "improving the end user's experience" and blah
blah blah, without ever mentioning the word Linux.
