- **HTTP Status:** 200 OK
- **Content:** Full Next.js application loading correctly
- **Headers:** Proper security headers present (X-Frame-Options, X-Content-Type-Options, Referrer-Policy)

### External HTTPS Access

#### Primary Domain (https://www.chorus.services)
- **Status:** ✅ OPERATIONAL  
- **Response Time:** 69-76ms average
- **HTTP Protocol:** HTTP/2
- **SSL Certificate:** Valid (0 = success)
- **DNS Resolution:** 5-6ms
- **TCP Connection:** 6-7ms
- **SSL Handshake:** 43-58ms

#### Redirect Domain (https://chorus.services)
- **Status:** ✅ OPERATIONAL
- **HTTP Status:** 307 Temporary Redirect
- **Redirect Target:** https://www.chorus.services/
- **Redirect Time:** <1ms

### External IP Access (202.171.184.242:3100)
- **Status:** ⚠️ BLOCKED (Expected - firewall protection)
- **Note:** Direct IP access blocked by security configuration (normal for production)

## Performance Metrics

### Response Time Analysis
| Endpoint | Min | Max | Average | Protocol |
|----------|-----|-----|---------|----------|
| localhost:3100 | 8.6ms | 14.6ms | 10.9ms | HTTP/1.1 |
| www.chorus.services | 69.2ms | 76.2ms | 73.2ms | HTTP/2 |

### Content Delivery Performance
- **Compressed Size:** 20,464 bytes (87% compression ratio)
- **Uncompressed Size:** 162,285 bytes
- **Transfer Speed:** 361KB/s (compressed), 2.5MB/s (uncompressed)
- **Compression:** Gzip enabled and working efficiently

### Caching Configuration
- **Cache-Control:** `s-maxage=31536000, stale-while-revalidate`
- **ETag:** `"cjhbuylf93h0q"` (consistent across requests)
- **Next.js Cache Status:** HIT (optimal caching performance)

## SSL/TLS Configuration

### Certificate Details
- **Certificate Authority:** Let's Encrypt
- **Certificate Resolver:** letsencryptresolver
- **SSL Verification:** ✅ Valid (result code: 0)
- **Protocol:** TLS with HTTP/2 support
- **Security Headers:** Properly configured

### Traefik Configuration
- **Routing Rule:** `Host(\`www.chorus.services\`) || Host(\`chorus.services\`)`
- **Entrypoint:** web-secured (HTTPS)
- **Middleware:** chorus-redirect (apex → www redirect)
- **Load Balancer:** Configured with passhostheader=true

## Load Balancing Assessment

### Service Discovery
- **Replicas:** 2 containers distributed across available nodes
- **Load Balancer:** Docker Swarm ingress with VIP mode
- **Health Checks:** Container-level health monitoring
- **Distribution:** Even traffic distribution confirmed

### Container Health
All containers show consistent startup patterns:
- Next.js runtime initialization: ~44-48ms
- Network binding: 0.0.0.0:80 (all interfaces)
- Ready state: Achieved within <50ms

## Security Validation

### HTTP Security Headers
```
X-Frame-Options: DENY
X-Content-Type-Options: nosniff
Referrer-Policy: strict-origin-when-cross-origin
```

### Network Security
- External IP direct access blocked (appropriate security posture)
- HTTPS-only access enforced through Traefik
- Proper certificate chain validation

## Optimization Recommendations

### Performance Optimizations
1. **Compression Ratio Excellent:** 87% compression achieved (20KB vs 162KB)
2. **Caching Strategy Optimal:** Long-term caching with stale-while-revalidate
3. **HTTP/2 Benefits:** Protocol upgrade providing multiplexing advantages

### Infrastructure Optimizations
1. **Memory Allocation:** Current 128MiB limit appropriate for Next.js workload
2. **Replica Count:** 2 replicas providing adequate redundancy for current load
3. **Health Check Timing:** Container startup time <50ms is excellent

### Monitoring Recommendations
1. **Response Time Monitoring:** Set alerts for >100ms average response time
2. **SSL Certificate Monitoring:** Monitor certificate expiration (Let's Encrypt 90-day cycle)
3. **Cache Hit Ratio:** Monitor Next.js cache performance metrics

### Minor Issues Identified
1. **Next.js Metadata Warnings:** Viewport/themeColor metadata should be moved to viewport export
   - Impact: Minimal (development warnings only)
   - Action: Update Next.js metadata configuration

## Conclusion

The CHORUS Services website deployment is **FULLY OPERATIONAL** with excellent performance characteristics:

- ✅ All critical endpoints responding correctly
- ✅ SSL certificates valid and properly configured
- ✅ Load balancing and redundancy working
- ✅ Performance within acceptable ranges (10-75ms)
