24/7 Heartbeat Uptime Monitor

Multi-region ping monitoring that measures response latency, status codes, and SSL expiration countdowns.

Technical Scope & Verification Behavior

Automated Inspection Checks (8)
Passive URL parameter fuzzing
Non-destructive boundary tests
Header & cookie flag assertions
Differential latency timing

Health Check Route Implementation

patch.diff (typescript)
--- a/handler.typescript (Vulnerable)
// No dedicated health check endpoint
+++ b/handler.typescript (Remediated)
export async function GET() {
  const dbOk = await checkDbHealth();
  return Response.json({ status: dbOk ? 'ok' : 'degraded' }, { status: dbOk ? 200 : 503 });
}

Provide a dedicated /api/health endpoint that validates database and critical backend dependencies for uptime probers.
