It's related to business choices that affect users in china, which is a huge slice of the playerbase. Instead of providing chinese servers, Bluehole or possibly the new PUBG corp have given ingame ad space, something people already took issue with over the gamescom promotion, to "Internet booster services" pissing off a ton of chinese gamers. So now everyone can suffer since current server structure can't handle peak loads and they don't want more servers for everyone.
