2026-02-02: Nonprod Elastic cluster unhealthy.

Nonprod Elastic cluster unhealthy. (Severity 3)

Problem: The nonprod Elasticsearch cluster is unhealthy, with one node unresponsive and another under critical disk pressure.

Impact: This could impact ingest and search reliability for nonprod workloads, with several primary and replica shards unavailable.

Causes: Node 79 in the nonprod Elasticsearch cluster is unresponsive, and node 75 is experiencing critical disk pressure (93% disk usage).

Response strategy: We initiated a forceful cluster restart through the Elastic Cloud portal, but progress is stalled. We opened a support case with Elastic to resolve the unresponsive node and restore cluster health.
