At around 5am UTC, the CEO of Binance, Changpeng Zhao, informed loyal clients of the exchange, that they were having issues with one of their Databases. The tweet went on to explain that a number of API users will not be able to see their orders correctly. Regular users of the Web application and mobile app were not affected by the issue but an engine restart was required. The exact tweet can be found below.
We are experiencing an issue after a DB fail over. A small number of API users won't see their orders correctly. UI (Web, APP) users are fine. An engine restart is required to fix the issue. We will halt trading for a engine restart in about 30 minutes, lasting about 60 min.
