PUBG Corp Attempting to Fix Connection Issue in Nordic and CIS Regions
Besides the problems from logging in, this is not an indication of the latest rumor. PUBG is not shutting down. Rumors to the contrary are completely without basis in fact. The rumors in question have been applied haphazardly to several of the music successful ongoing games in the world, including Minecraft, Roblox and Fortnite.
Rumors of Minecraft's imminent end emerged online first, spurred on by a fake news article created as a prank. Internet trolls applied the same treatment to Roblox shortly thereafter, writing a transparently fake news story to stoke the rumor mill.
By the time the treatment was applied to Fortnite, the rumor mongers did not even bother to create a fake news article to pretend at legitimacy. The same is true in the case of the PUBG rumors.
