We're investigating an issue with Snowflake in US region which causes some Storage operations with tables to be stuck in processing state. This can cause jobs to be executing longer than expected or seemingly "forever". Terminating and restarting the job does not help in such a case. Only certain projects are affected.
Next update in 1 hour or as new information becomes available.
Update 10:50 UTC: The stuck jobs are unblocked now and should be finishing, we're monitoring the situation if the issue reappears. A post mortem will be published once we get an RCA from Snowflake.
