On 27 December at 18:38 UTC, BitMEX experienced a minor outage for approximately 1 minute whereby the trading engine was unavailable. During this time, market data updates were not published over the Websocket API.
Additionally, REST API queries for trading related data (read-only HTTP GET requests, not order management requests) took longer to return than usual over a period of 23 minutes from 18:13 UTC to 18:36 UTC.
The root causes of both issues have been identified and we are working on permanent fixes to prevent a recurrence. Updates will follow in the future.
We apologise for the inconvenience. If you have any questions, please contact customer support.
