Yep. Other people have seen the same thing. Previous discussion on HN: https://news.ycombinator.com/item?id=11851529 https://news.ycombinator.com/item?id=11851529 The first post in the article describes the exact symptoms I see. I see the connections only when my wife's computer is on (but not always, maybe once a week), and when they occur, there's a Windows system process churning away on it. Connections are always to Akamai servers (confirmed with whois) on port 80, both v4 and v6 (I have native v6 via Comcast). Didn't occur until she upgraded to Windows 10 a couple months ago (she was on 8 before). To be fair, this might really be an Akamai thing, with MS just using their client blindly. But neither OS X nor Linux nor Windows 8 does this to my network, so I think it's fair to blame MS for this.
