If you're thinking about flightradar24, then it's more likely that the user supplying the data is just offline. Data is supplied both from their own radars and from enthusiast all over the world. Some are online 24/7 while other come and go.
Quote: Last week Flightradar24.com had coverage over my house, but not any more. Why?Flightradar24.com is a network of receivers around the world. Some receivers are online 24/7 and others are only online from time to time. There are many reasons why a receiver is offline. There can be a technical problems with the receiver, with the antenna or the computer. It can also be a problem with the Internet connection to the receiver. Or the owner of the receiver has closed down his receiver and moved to another location. With over 200 receivers connected to the network, Flightradar24.com cannot tell why different receivers are offline, and when they will be back online. If you want to be sure to have coverage in your area, buy one receiver and connect it to Flightradar24.com
