Thousands of Russian gamers are unable to join matches
A few days ago Russian court has approved sanctions against messenger Telegram which resulted in blocking millions of IP adresses including Amazon servers. This sanctions have been taken against the messenger due to their refusal to share keys that would allow Russian intelligence agencies to get access to users chats. This actions has resulted in several companies to stop their activities due to these actions. The messenger however still is available for Russian audience.
PUBG servers have moved from Amazon servers to Microsoft Azure and some of their IP adresses have been blocked by Roskomnadzor(the organization that regulates internet policies in Russia) thats why the situation is rather grim for Russian users.
