Upbit Delays Trading Restart by an Hour After Finding Instability

South Korean exchange Upbit delayed the reopening of its Korean won (KRW), Bitcoin (BTC) and USDT markets to 5 p.m. ET Sunday, Nov. 8 (22:00 UTC), after finding instability during service recovery.

The exchange began server maintenance at noon ET Sunday, Nov. 8, equivalent to 2 a.m. Monday in South Korea, and initially estimated the work would take about five hours. Upbit later announced that maintenance had finished ahead of schedule and set a phased return to trading for 4 p.m. ET. It then moved the market opening back by an hour despite the early completion of server work.

The maintenance finish and trading return remained separate steps: the revised notice came after server work was complete but before the affected markets reopened. The updated schedule covers the Korean won, BTC and USDT markets. Deposits and withdrawals are set to resume in stages after trading restarts and queued orders are processed. Upbit did not provide a separate clock time for those services.
