BitMEX experienced two unrelated service outages back on January 9. The information was released by the company in its blog post on January 11. According to BitMEX, at 02:44:10 UTC the WebSocket API saw a degradation in performance for a minute.
During that time, 7% of the commands sent by clients failed. Apparently, the connections continued undergoing a 1% failure rate of commands for a longer period of time. The situation ended once the servers recovered at 02:47:00 UTC.
The company explains that clients could also have seen an increase in response times for some market data REST endpoints up. BitMEX explains that this situation occurred due to a rolling restart of the API servers in a very short period of time.
Additionally, due to data replay complications, clients would have observed a lack of updates over the WebSocket API for periods of 30 seconds between 05:48:10 UTC and 06:10:10 UTC. During these events that are not comfortable for anyone, no data was lost and additional safety mechanisms were deployed to avoid these situations in the future.
As the exchange was able to discover why these situations occurred, it is possible to take the necessary measures to mitigate these problems.
On 27 December at 18:38 UTC, BitMEX experienced a minor outage for approximately 1 minute whereby the trading engine was unavailable. We apologise for the inconvenience.
