We are experiencing a minor slow down of performance on Snowflake in the EU Region and are currently investigating.
There are no job failures or increased queue backlog but everything seems to run slightly slower.
The next update will be in 120 minutes or as new information becomes available.
Update October 26 2020, 12:50 UTC: Performance has for the most part recovered, the rate of long execution of some queries has dropped significantly, but hasn't quite completely disappeared. We will update again if the issue re-surfaces.
