Since 0600 UTC we have observed cluster node connectivity issues isolated to a single availability zone, GCP europe-west2-b. Atlas clusters are distributed across multiple AZs and 3-node clusters can continue to serve reads and writes from nodes in the other 2 Availability Zones in this region. We are working with our partners to resolve the cause of the issue and restore service to the affected nodes.
