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.
