Sprint is throttling Microsoft’s Skype service, study finds

A glitch: If you can't make Skype calls, it could be due to the fact that your status is shown as offline even when logged in.

Sprint Corp has been slowing traffic to Microsoft Corp’s Internet-based video chat service Skype, according to new findings from an ongoing study by Northeastern University and the University of Massachusetts. 

More than 100,000 consumers have used the researchers’ Wehe smartphone app to test Internet connections. Information from those tests are aggregated and analysed by the researchers to check if data speeds are being slowed, or throttled, for specific mobile services.
