g9i.sevmob.com

When browsing my local newspaper's website on my iPhone 5s, I get redirected to the site in the title, g9i.sevmob.com, and it's usually a blank page. It was happening awhile back but stopped for awhile. It's happening again now. Occasionally it'll also redirect to the App store for a particular game, although I don't think this "malware" or whatever it is is connected to that game. It also only appears to happen when I'm using mobile data (T-mobile) and not on wifi.

A web search shows that this is not a isolated problem. Anyone else here experiencing this?
