Detailed Status Change Process

Phase 1: Registration & Configuration (January 2020)

1. Domain Registration: User registers example.com with GoDaddy
2. DNS Configuration: Set A record pointing to server IP
3. SSL Configuration: Apply for and install SSL certificate
4. Status Change: Available → Registered → Active

Phase 2: Normal Operations (2020-2022)

1. Website Operations: Domain resolves normally, SSL certificate valid
2. Certificate Renewal: Periodic SSL certificate updates
3. Monitoring & Maintenance: Continuous monitoring of domain and SSL status
4. Status: Maintains Active status

Phase 3: Expiration Handling (2022-2023)

1. Expiration Notice: Registrar sends renewal notifications
2. Domain Expiration: Failed to renew on time, domain expires
3. Grace Period: Renewal completed within grace period
4. Status Change: Active → Pre-Expiry → Expired → Grace → Renewed

SSL Certificate and Domain Status Relationship

Domain status directly affects SSL certificate validity:

    A[Domain Active] --> B[SSL Certificate Valid]
    C[Domain Expired] --> D[SSL Certificate Invalid]
    E[Domain Grace Period] --> F[SSL Certificate Invalid]
    G[Domain Pending Delete] --> H[SSL Certificate Invalid]
    
    B --> I[Website Normal Access]
    D --> J[Browser Security Warning]
    F --> K[Website Inaccessible]
    H --> L[Domain Not Found]

Best Practice Recommendations

1. Domain Management

• Set up auto-renewal to avoid accidental expiration
• Check domain expiration dates 30-60 days in advance
• Keep registration information updated

2. SSL Certificate Management

• Configure SSL certificate expiration monitoring
• Use auto-renewing certificates (like Let's Encrypt)
• Regularly check certificate chain integrity

3. Monitoring & Alerts

• Use tools like ZSSL to monitor domain and SSL status
• Set up multi-channel reminders (email, SMS, DingTalk, etc.)
• Maintain a domain asset inventory

4. Emergency Response

• Prepare emergency plans for domain expiration
• Understand different registrars' grace period policies
• Keep backup plans for important domains

Recommended Tools

• ZSSL Platform: Provides domain SSL certificate checking and monitoring services
• Bulk Domain Checker: Supports batch checking of multiple domain statuses
• SSL Certificate Badges: Display website SSL security status
• Expiration Reminder Service: Automated domain and SSL certificate expiration reminders

By understanding the complete lifecycle of a domain name, you can better manage your domain assets and ensure continuous, stable website operations.
