Here’s how to find out if PUBG’s servers are down.
PUBG Servers Are Too Busy: How to Tell if the PUBG Servers Are Down
PUBG Corp will generally try to update players on server status as quickly as possible whenever problems arise. To check for an official PUBG Corp statement about what appears to be server trouble, head to the @PUBG_Supprt Twitter account. A relevant tweet there can clarify what the problem is, but it’s not the be-all and end-all of whether something is wrong.
Third party sites such as IsTheServiceDown and DownDetector can show problems even before PUBG Corp has times to respond to them. If PUBG Corp has yet to make a statement but either of these sites is showing a problem, it’s likely that statement is forthcoming.
