Fivetran: Snowflake destinations failing with error code 503
Incident
Report for Fivetran
Resolved
This incident has been resolved. We have observed that error rates are returning to normal levels, and affected connectors are syncing successfully.
Incident Summary
Description:
We identified an issue for Snowflake destinations, which resulted in syncs failing with a "JDBC driver encountered communication error. Message: HTTP status=503." error.
Timeline:
This issue began on 2024-09-03 at 3:11 PM UTC and was resolved on 2024-09-04 at 11:00 AM UTC.
Cause:
Upgrading the Snowflake JDBC driver caused a number of connectors to fail intermittently or constantly, particularly in destinations containing a large number of connectors syncing simultaneously.
Resolution:
Downgrading the driver allowed affected connectors to resume operating normally. We will work with Snowflake to identify the root cause of the issue and address it before performing this upgrade again.
