Couchbase Capella - Capella Operations Impacted by GCP us-central1 region capacity issues – Incident details

Update: GCP us-central1 Compute Engine capacity constraints continue. Live provider status is reflected on the GCP components on this page.

Customer Impact:

• Affected Operations: Cluster creation, turn-on, upgrades, scaling, and bucket backups in us-central1 may fail while constraints last.

• Backups: Couchbase Support will perform cluster backups where customer backups fail.

Guidance: Standing recommendations and the actions taken by Couchbase are published in the general notice "GCP us-central1 Capacity Constraints: Guidance for Capella Customers" on this page, directly below this incident, and will be kept current there.

We will post here when GCP restores capacity in the region.

Update: Ongoing Mitigation for GCP us-central1 Capacity Constraints

Actions Taken by Couchbase:

• Instance Capacity Management: We executed capacity reservations where available to help retain and protect resources allocated to active Capella clusters.

• Region Tagging: We have flagged us-central1 as capacity-constrained in our control plane to proactively manage deployment guidance and reduce operational friction.

• Platform Enhancements: We are accelerating technical updates, including automated multi-instance fallback capabilities and support for GCP’s newer generation machine families, to unlock broader capacity options and enhance platform resilience.
  

Recommended Customer Guidance:

• Existing Clusters: We recommend minimizing non-essential cluster modifications—such as scaling, node changes, or pausing/resuming—where possible, as these lifecycle operations may experience failures due to underlying GCP instance capacity constraints.

• New Deployments: Consider selecting alternate GCP regions for new cluster creation where feasible.

• Backups: Continue maintaining regular cluster snapshot backups as a standard high-availability best practice.

We remain in close coordination with the GCP team and will share further updates as additional mitigations are released or regional capacity conditions evolve.
