Chan Chang’s CEO Zhao Changpeng just said on Twitter: “We have encountered a server problem that affects all withdrawals. It may take 1-2 hours (rough estimate) to fix it. We are very clear about the problem and know how to solve it. In researching more accurate ETA (repair completion time), we will follow up the information in time. I am sorry for the inconvenience. The transaction is not affected and the funds are safe."
