Snowflake shows resilience during AWS outage

"Snowgrid has been available since 2022 and offers organizations the ability to replicate data and workloads across multiple cloud regions on AWS, Microsoft Azure, and Google Cloud. When a failure occurs, a pre-set failover scenario can be activated manually or automatically. The platform ensures that workloads resume at a secondary location without data loss or duplication. Applications and dashboards are reconnected through automatic DNS updates. This usually happens without noticeable downtime for end users."

"The AWS outage was caused by a problem in the DNS infrastructure of the U.S. East 1 region, according to SiliconAngle. As a result, control plane services were also unavailable, even for customers with workloads spread across multiple availability zones. SiliconANGLE notes that the incident makes it clear that availability zones do not offer complete protection. Services such as DNS or identity management are shared across a region, so a failure at that level can affect all zones simultaneously."

"While organizations experienced disruption, Snowflake reported that more than 300 customer workloads continued to run without interruption. This was thanks to its Snowgrid technology. According to Snowflake, these workloads automatically switched to alternative regions or clouds, allowing business processes to continue largely uninterrupted. SiliconANGLE writes that Snowflake took the opportunity to remind customers that an outage does not necessarily lead to a business crisis, provided a well-thought-out continuity strategy has been put in place."

An AWS DNS infrastructure problem in the U.S. East 1 region caused control plane services to become unavailable, affecting customers across availability zones. More than 300 Snowflake customer workloads continued running without interruption due to Snowgrid, which automatically switched workloads to alternative regions or clouds. Snowgrid, available since 2022, replicates data and workloads across AWS, Microsoft Azure, and Google Cloud and supports manual or automatic pre-set failover scenarios that resume workloads at secondary locations without data loss or duplication. Applications and dashboards reconnect through automatic DNS updates, typically with only brief interruptions for end users.
