5 hour maintenance ongoing
While PUBG servers have been turned of for the scheduled maintenance it's time to step down from PUBG for a few days while all the consequences of the update would be sorted out. The maintenance itself is scheduled to be performed within a few hours and has already started.
PC Players: Live servers will enter routine maintenance for 5 hours starting Nov 6 4:30pm PST / Nov 7 1:30am CET / Nov 7 9:30am KST.— PUBG Help (@PUBG_help) 6 ноября 2018 г.
Maintenance is aimed for the PC Update #23 and would most likely cause issues in the game performance.
