Identified -
We've identified a particularly costly query pattern and we are currently writing a fix to limit its impact. Performance is expected to remain spotty for a while until this is ready. We're exploring alternative mitigation mechanisms at the same time.

Investigating -
Our query engine is currently under pressure and reporting longer delays to complete queries and more elevated failure rates. We are currently investigating possible sources behind this.
