We were experiencing issues with write operations in one of our data warehouses between 7.00 PM on January 2 and 2.00 AM on January 3 EDT (1.00 AM and 8.00 AM on January 3 CET). During this time, issues appeared for certain users with functions such as executing scheduled syncs, creating new metrics, previewing data in the metric builder, purging data. This has been resolved.
If you should still experience any irregular behaviour, please reach out to our Support services.
