13.1 Update goes live August 4
Today, the developers announced the exact time when the new patch number 13.1 will be moved from the test to the main PlayerUnknown's Battlegrounds client. On Wednesday morning, KRAFTON will shut down the game's main servers for the technical work required to install the update.
[PC] Live servers will enter maintenance for 8 hours starting Aug 3rd, 5:30pm PDT / Aug 4th, 2:30am CEST / Aug 4th, 9:30am KST. Once complete, Update 13.1 will be available on Live Servers.
The expected time for big updates is around 8 hours but usually is dealt with in a few hours less.
