Investigating
Since approx 07:10 UTC REST API queries for historical data are missing the past hour's worth of data due to an issue when writing the data to disk. The source data isn't impacted i.e. there is no data loss, however the data isn't currently available to the REST API. We've identified the issue and are currently recovering full functionality.
