There's a discussion about GPSJam, which is where he got that map, from a few months ago here: https://news.ycombinator.com/item?id=32245346 https://news.ycombinator.com/item?id=32245346 Sometimes the interference seen on those maps does affect phones, sometimes it doesn't. Coincidentally there's a huge region of GPS (at least) interference this week over the New Mexico area, from a military test. My guess is that people on the ground won't be affected, unless maybe they're very close to White Sands Missile Range between 18:30 and 22:30 GMT.
