Official Announcement Regarding ZB Downtime Incident
According to ZB's official announcement, on September 17, 2020 at 2:40 AM, ZB began technical upgrades. Subsequently, a capacity expansion operation error occurred. A partition increase operation for user funds was performed without stopping service, causing data disorder within about 10 minutes and a price decline in certain altcoin markets. Within about 10 minutes after the incident, operators immediately stopped trading operations. To counter market rumors about losses, ZB disclosed the hot wallet withdrawal address from the time of the price anomaly to when all operations were stopped (ZB has very strict risk controls).
