We are investigating connection errors in projects with Snowflake backend. It is related to today's snowflake maintenance, we are in contact with their support.
We will update this post when we have more information. Sorry for any inconvenience.
UPDATE 09:30 PM PDT Storage is fixed and failed orchestrations were restarted. We are working on Snowflake transformations fix.
UPDATE 10:15 PM PDT Snowflake transformations are also working. Snowflake did the rollback of release which caused problems.
