What kind of infrastructure changes has Microsoft made?

It's been one year since Microsoft announced plans to acquire Skype and seven months since regulatory bodies approved the transaction, enabling Microsoft to take control officially of the VoIP (Voice over Internet Protocol) vendor.

I wondered last year if and when Microsoft would put its stamp on Skype's back-end systems. With prior acquisitions, Microsoft at times lets newly acquired companies continue to run the same hardware, software and services they've been using previously a Redmond take-over. On the whole, over time, nevertheless, Microsoft tends to try to align the infrastructure of companies they acquire with the rest of the servers powering the company's other business units.

Classic example

Hotmail is a classic example. The Hotmail servers were running FreeBSD for years afterwards Microsoft began attempting to move them to Windows 2000.

A quick search on the Microsoft Jobs boards indicates that Skype is nevertheless pretty much a PHP, Perl and Python shop. One open Skype job specified that either Linux or Windows experience would be acceptable.
