In the early morning Snowflake had an incident in their US West region which caused a large backlog of job processing in Keboola's US Region. The jobs were all eventually processed, but they may have taken much longer than what you normally experience.
The buildup in our queue began just before 2:00AM CEST and started to ease after 4:30AM CEST.
Please refer to the above link for further information, and we will add a link to the RCA when it becomes available.
