457. Very Briefly: Microsoft has a Tor exit node?

Whenever I play around with Tor I use ipchicken.com or whatsmyip.org to make sure that I'm indeed using a proxy. I also normally do a whois on the IP address, so see who's running the exit node.

Today I ended up with the IP address 168.61.8.22.

That Microsoft is listed as the organisation doesn't necessarily mean that they are running the node (could be a hosting company) but it still seems that this might actually be MS running this one. Maybe it's just for research purposes, but it still seemed a bit surprising.

Microsoft as a company isn't exactly known for doing things out of the goodness of their hearts. Oh well.
