Strava question.

Yes but its only happened once.

Phones have something called A-GPS, assisted GPS. When Google did streetview they also scanned WIFI SSID when recording images and location. It is used in A-GPS to get a quick location by picking up any SSID in range. I suspect the SSID at the COOP was the same as at the other COOP, so Android said, you are there not here.
