2025-10-21: No traffic reported by primary_server SLI for redis-registry-cache in main stage

No traffic reported by primary_server SLI for redis-registry-cache in main stage (Severity 3 (Medium))

Problem: The primary_server component of the redis-registry-cache system in the main stage has not reported any traffic for the past 30 minutes after previously receiving traffic.

Impact: No traffic is being reported for the redis-registry-cache service in the main stage. There is no user-facing impact, as this was a planned removal.

Causes: This occurred because the redis-registry-cache was decommissioned as part of a planned change.

Response strategy: This was resolved by decommissioning the redis-registry-cache service and its associated metrics as planned.
