Lesson: Zonal outages can impact network connectivity across multiple regions for stretched cluster configurations.

What happened

Incident Report Summary On Tuesday, 14 July 2026 10:00 PT, Google Cloud VMware Engine (GCVE) Stretched Cluster customers in the australia-southeast2 and europe-west3 zones experienced inter-site communication failures. The disruption was traced to a network configuration update that introduced a conflict, causing inter-site communication failures, which triggered VMware Stretched Cluster failover events. Google engineers successfully mitigated the impact by rolling back the issue-causing configuration change and resetting the network state. We sincerely apologize for the disruption this incident caused to your business. We know how much you rely on Google Cloud, and we regret the impact on your productivity. We are working to address the root cause and prevent this from occurring in the future. Root Cause A network configuration update intended to prepare the cloud network infrastructure for new capabilities was deployed to the foundational network control plane. While the configuration payload itself was structurally valid, it exposed an implementation gap within the control plane's routing logic. This logical gap caused the underlying network hosts to misconfigure program routing

We are working to address the root cause and prevent this from occurring in the future. Root Cause A network configuration update intended to prepare the cloud network infrastructure for new capabilities was deployed to the foundational network control plane. While the configuration payload itself was structurally valid, it exposed an implementation gap within the control plane's routing logic. This logical gap caused the underlying network hosts to misconfigure program routing tables. As a result, traffic destined for the private IP address space used by GCVE Stretched Clusters was dropped. Because Stretched Clusters rely on this private address space to establish routing sessions for inter-zonal connectivity, the traffic drops severed communications between the active z

   **Summary** Google Cloud VMware Engine (GCVE) Stretched Cluster customers are experiencing zonal outages impacting network connectivity across multiple regions. **Description** We are experiencing an inter-site communication issue with Google Cloud VMware Engine (GCVE) stretched cluster customers beginning Tuesday, 2026-07-14 at 10:00 PDT. We have identified the customers that are affected by this issue and we are working with them on mitigation. Our investigation has identified underlying inter-zone communication failures and Border Gateway Protocol (BGP) session flapping between cluster zones. Specifically, network connectivity has been lost between the affected zones and the witness appliance. Because the witness appliance is currently unreachable, the cluster zones are unable to safely synchronize state. As a result, VMs on the affected sites are becoming isolated and may be left without writable data. **Failover / VM Migration:** Migrating affected VMs to the healthy, secondary zone of your stretch cluster remains the primary mitigation strategy. Because of the complexities surrounding failover risks and secondary zone health, we highly encourage you to open a ticket with Google Cloud Support if you are severely impacted.

    **Summary** Google Cloud VMware Engine (GCVE) Stretched Cluster customers are experiencing zonal outages impacting network connectivity across multiple regions. **Description** We are experiencing an inter-site communication issue with Google Cloud VMware Engine (GCVE) stretched cluster customers beginning Tuesday, 2026-07-14 at 10:00 PDT. We have identified the customers that are affected by this issue and we are working with them on mitigation. Our preliminary investigation indicates this is stemming from an underlying network connectivity issue affecting the infrastructure that links the zones within a stretch cluster. This disruption is causing synchronization issues between the affected zones. We believe Storage and Compute services remain unaffected, and VMs are running as expected, though connectivity to them may be degraded. We will provide another update by Tuesday, 2026-07-14 15:00 PDT with current details. **Customer Symptoms** Some GCVE customers using Stretched Cluster may experience inter-site communication failures to their GCVE environments within the affected zones. **Workaround** While we work on restoring full connectivity, we recommend the following workarounds to restore access to your workloads: - VM Migration (recommended): Where possible, migrate your affected VMs to the healthy and unaffected side of the stretch cluster.
