Apple

My boyfriend went back to his city for the remainder of thanksgiving break and I decided to check his location. I know where his mom lives so when I go to check his location, I can see if he’s at home or not but this time when I went to look, he was at this random house, and the location said from four hours ago. I repeatedly tried to update it and even restarted my phone a couple of times, but it stayed the same. I then texted him and my message didn’t go through. What does this mean?
