For the past few days the “global sever” system has been troublesome and has been going from green to red quite a number of times in every flight. The first time I experienced this was last Saturday. A few trends/key things I’ve noticed is that it is mostly only on long haul flights, and it is usually towards the end of the long haul flights. The beginning portion is completely fine. I checked my WiFi connection and it remains stable, and so is my device. I’m still able to see other planes and communicate with ATC so I do not believe it to be an issue from my internet or device. I was wondering, what might be causing this issue and how can it be resolved?
