    GCP experienced an outage which impacted our ability to access GCS object storage and GCR image repository services. This resulted in some Zilliz Cloud clusters to be unavailable in the GCP regions of gcp-us-east4, gcp-us-central1, and gcp-us-asia-southeast1. Cluster creation and edit operations were also impacted in those regions. As of now, GCP services have fully recovered, and our services have fully recovered as well.
