This week PlayerUnknown's Battlegrounds developers won't shut down live game servers for maintenance. They shared this information on their twitter.
PC Players: There will be no routine live server maintenance this week.— PUBG Support (@PUBG_Support) November 11, 2019
Backend stability improvements will be implemented without downtime at Nov 12 6pm PST / Nov 13 3am CET / Nov 13 11am KST.
The developers promised this month to fix the critical bug with sound, which has been discovered and documented by WackyJacky101 in July. The essence of this error is that some surfaces in PlayerUnknown's Battlegrounds completely absorb the sounds of walking.
