Suspicous activty with UAL835

Hi there Sorry for the probable stupid post (I`m under 18yrs, but I know alot about planes and crashes)
But there is a flight, UAL835 has been in the same place for about a day(I learned about 835 from airliners.net)and it has been in the same place for awile north of canada, did something happen to it or what?

Not suspicious at all, just left flightaware’s tracking area, as it does every day.

When you see something like this, it helps to check previous days or other aircraft on the same route - for example, the American flight - flightaware.com/live/flight/AAL2 … /KORD/ZSPD
