Identified

ClickHouse Cloud has identified an issue with our auto-scaling process in all regions. For services which had not manually adjusted their auto-scaler slider and were using the default (and which were not currently idled), those services could have had their scaler sizing reduced by this issue. We are actively pushing out a fix to all regions now.
