There was a short Snowflake outage between 10:30 and 10:35 CEST (09:30am and 09:35am UTC) in US region.
- Sandboxes might have lost their data and worksheets
- Transformation jobs might have finished with an error
- Async data loads and exports were unaffected
We're investigating the impact and root cause and will update this post as soon as we know more. Snowflake is now back fully operational.
UPDATE Jan 30 2018: Snowflake released their RCA.
