If your domain name is blocked, you need to identify the cause and take appropriate actions. Common reasons for a blocked domain include security violations, illegal content, violation of platform policies, or being flagged by DNS services or internet service providers (ISPs).
-
Identify the Block Reason:
- Check if the block is from your hosting provider, DNS service, or ISP.
- Use tools like MXToolbox or DNS Checker to see if the domain is blocked globally or in specific regions.
- Review any notifications or emails from your hosting provider or domain registrar.
-
Resolve the Issue:
- If the block is due to security issues (e.g., malware or phishing), clean your website and request a review from the blocking authority.
- If the block is due to policy violations, update your content to comply with the rules.
- If the block is accidental (e.g., false positive), contact the blocking party (e.g., your hosting provider or ISP) to request removal.
-
Use Alternative DNS Services:
- If the block is caused by a specific DNS service, switch to a different DNS provider. For example, you can use Tencent Cloud’s DNSPod for reliable and fast DNS resolution.
-
Check for Regional Restrictions:
- Some domains are blocked in specific countries due to local regulations. Use a CDN or proxy service (like Tencent Cloud’s Global Accelerator) to route traffic through unrestricted regions.
-
Prevent Future Blocks:
- Regularly monitor your domain’s reputation using tools like Google Safe Browsing or VirusTotal.
- Ensure your website complies with legal and platform policies.
- Use Tencent Cloud’s Web Application Firewall (WAF) to protect against malicious attacks and reduce the risk of being blocked.
Example: If your e-commerce site is blocked due to suspected fraud, use Tencent Cloud’s WAF to filter malicious traffic and submit a review request to your hosting provider.
