There are a few ways for PUBG players to check if the servers are up and running if troubles occur.
There is a website PUBG Mobile players can use to check the server status of the game. Players can go to this website and see if there are any major problems with PUBG Mobile servers. It works similarly to DownDetector, which players use to find out the server status of PUBG on PC or console. Reports from players who are apparently experiencing a problems with the game will be shown.
It will also show if there are more reports in certain countries over others, which will help players see if all servers are down or if only certain regions are experiencing problems.
