1. Error Handling

Problem:

• Initially, within the status code section, you will observe a time-series depiction of errors, allowing the identification of anomalies in their behavior. For instance, higher occurrences of 404 errors might signify an abnormal trend. Users might encounter 404 errors when accessing content through Medianova CDN.

Solution:

1. Log in to the Medianova Cloud panel.

2. In the Analytics tab of the Medianova Cloud panel, review the logs in the Error Logs menu to identify which file or resource triggered the 404 error.

3. Clear the cache in the Medianova Cloud panel. 404 errors may sometimes be caused by cached content, so clearing the cache and trying again is crucial. Clear the Medianova CDN cache to ensure the latest version of the resource is served.

4. If the CDN utilizes an origin server, ensure that it is correctly configured. Verify that the files are in the correct location on the origin server. If recent changes were made, update links on your website to reflect the new resource paths provided by Medianova CDN.

5. If your site is accessed via HTTPS, confirm that the files are being served correctly over HTTPS. Mixed content issues can result in 404 errors.

2. Slow Loading Issues

Problem:

Users experience slow loading times for content delivered via Medianova CDN.

Solution:

1. Review the cache settings in the Caching tab of the Cloud panel. Effective cache usage can improve page loading times. Test by clearing the cache if necessary.

2. Optimize images, scripts, and stylesheets to reduce file sizes and enhance loading speed. Review the Gzip compression settings in the Cloud panel. Compression reduces data transfer, aiding in faster page loading.

3. If dynamic content is utilized, configure the CDN panel for dynamic content appropriately. This can contribute to faster loading of dynamic content.

3. Security Violations and Measures

Problem:

Security issues or violations are detected within Medianova CDN.

Solution:

1. In the Analytics tab of the Cloud panel, navigate to the WAF menu and review the security logs. Examine the logs to identify the type of security breach that occurred and determine which resources or files were affected.

2. Check the WAF settings in the CDN panel. WAF provides a preemptive defense against potential threats. Update WAF settings if necessary.

3. If HTTPS is in use, review the SSL/TLS configurations in the CDN panel. Ensure that security protocols are up-to-date and correctly configured.

4. Inspect the IP whitelisting and blacklisting settings in the panel. If needed, take measures by adding trusted IPs to the whitelist or blacklisting potential threats.

4. SSL Configuration Errors

Problem:

Users experience SSL-related issues when accessing secure content.

Solution:

1. Review the SSL/TLS configurations in the Cloud panel. Ensure that certificates, keys, and other SSL/TLS settings are correctly configured. If the issue persists, check if the SSL certificate is still valid.

2. If the SSL certificate has expired or is nearing expiration, renewing the certificate ensures that you provide services with an up-to-date and valid certificate.

3. After updating SSL certificates, go to the CNAME & SSL tab in the resource to update the SSL for resources.

4. Check for mixed content errors, which are crucial for browser security. If the page contains content served over HTTPS alongside content served over HTTP, browsers may flag this as insecure.

5. Cache Invalidation Techniques

Problem:

Changes made to the origin content are not reflected immediately in the CDN.

Solution:

1. Review and adjust cache expiry settings for specific content types to ensure timely updates.

2. Use the settings in the "Caching" or "Purge" tabs in the Cloud panel. This allows for the immediate update of a specific file or page.

3. In the Cloud panel, you can perform a Wildcard Purge operation using the asterisk (*) in the "Purge" tab as well. You can explore the option to clear all content within a specific category or type using this method.
