Between 07:50 and 07:58 UTC on 27 June 2019, the following websocket API feeds were interrupted due to a complication during a planned upgrade of our market data distribution services:
Account, affiliate, execution, funds, instrument, margin, order, position, trade, transact, wallet Users of the BitMEX website may have noticed some data not updating during this period e.g. in the Recent Trades panel, Open Orders panel, Fills panel, and Position panel.
The following public feeds were unaffected during this period:
Funding, insurance, liquidation, settlement, impactQuote, impactQuoteBin1m, quote, quoteBin1m, quoteBin5m, quoteBin1h, quoteBin1d, tradeBin1m, tradeBin5m, tradeBin1h, tradeBin1d, orderBookL2_25, orderBook10, orderBookL2 During this period we continued to process order instructions and the trading engine was unaffected.
Due to this issue, data in a subset of data mirrors which service user REST API requests was left in an incomplete state. A side-effect of this was that some users observed stale open orders on the BitMEX website for orders which were already cancelled for a period of 90 minutes whilst data was being restored. Any API users that may be missing updates for this period can now backfill data via the REST API.
