Three Google Cloud services, including VMware Engine and NetApp Volumes, experienced a 15-hour outage in the europe-west4-a zone due to a cooling failure caused by an upstream utility grid electrical fault. Analysts highlight that despite cloud providers recommending multi-zone deployments for resilience, some specialized managed services can have single-datacenter dependencies within a zone, lacking transparency for customers.
Hyperscaler resilience claims are often misleading for specialized services, forcing customers to audit underlying infrastructure for hidden single points of failure.
