Resolved -
While resolving the problem, we had to replace some cluster resources. This appear to have caused some unexpected down-time for the MQTT server between 20:30 - 21:00 CET (UTC+01:00).
If you are writing data via MQTT with QoS setting 0 (fire and forget), or if the client lacks caching of meesages for when a connection can not be established, then you are adviced to check for gaps in your Clarify data for the relevant period.
Inputs written via our HTTP API does not appear to be affected.
The issue with query performance should now be resolved.
