 - **Services Monitored**:
   - asimonson.com
   - files.asimonson.com
   - git.asimonson.com
-  - pass.asimonson.com
-  - ssh.asimonson.com
 
 **Features**:
 - Tracks response times and HTTP status codes
 - Calculates uptime percentages for multiple time periods (24h, 7d, 30d, all-time)
 - Persists data to PostgreSQL (`service_checks` table) via `DATABASE_URL` env var
 - Gracefully degrades when no database is configured (local dev)

+  intervals, so `/api/status` can't silently keep serving old data as fresh
