"A software update knocked out Snowflake's cloud data platform in 10 of its 23 global regions for 13 hours on December 16, leaving customers unable to execute queries or ingest data. Customers saw "SQL execution internal error" messages when trying to query their data warehouses, according to Snowflake's incident report. The outage also disrupted Snowpipe and Snowpipe Streaming file ingestion, and data clustering appeared unhealthy. "Our initial investigation has identified that our most recent release introduced a backwards-incompatible database schema update," Snowflake wrote in the report."
""As a result, previous release packages errantly referenced the updated fields, resulting in version mismatch errors and causing operations to fail or take an extended amount of time to complete." The outage affected customers in Azure East US 2 in Virginia, AWS US West in Oregon, AWS Europe in Ireland, AWS Asia Pacific in Mumbai, Azure Switzerland North in Zürich, Google Cloud Platform Europe West 2 in London, Azure Southeast Asia in Singapore, Azure Mexico Central, and Azure Sweden Central, the report said."
On December 16 a software update caused Snowflake's cloud data platform to fail in 10 of 23 global regions for 13 hours, preventing query execution and file ingestion. Customers encountered "SQL execution internal error" messages while querying data warehouses, Snowpipe and Snowpipe Streaming ingestion were disrupted, and data clustering appeared unhealthy. The outage resulted from a backwards-incompatible database schema update in the most recent release, which previous release packages referenced, producing version mismatch errors that caused operations to fail or slow. Impacted regions spanned Azure, AWS, and GCP zones across multiple continents. Snowflake advised failover to non-impacted regions for replicated customers and promised a root cause analysis within five working days.
