Troubleshoot DNS Issues with the CDN
NetSuite provides CDN and caching services, which must be enabled in NetSuite. Third-party CDN and caching services aren't supported and must not be used because they can cause operational issues.
Content delivery networks (CDNs) are geographically distributed servers that specialize in delivering static content quickly. You can use CDNs to optimize the performance of your Commerce website by using them to cache things like images, search results, and SSP files. CDNs are external to NetSuite's caching infrastructure.
NetSuite SuiteCommerce uses a state-of-the-art content delivery network (CDN) to protect our customers and users from internet threats such as DDoS attacks, aggressive bots, and other fraudulent activities. NetSuite has set up and fine-tuned a wide range of protective measures for SuiteCommerce, like rate limiting, bot management, a web application firewall, IP reputation management, and geo-blocking based on Oracle policy. A team of network and security engineers monitors and updates these measures 24/7.
SuiteCommerce, SuiteCommerce Advanced, and SuiteCommerce MyAccount websites use Akamai as their CDN services provider.
Akamai inserts the original client IP in the True-Client-IP or X-Forwarded-For header. It isn't possible to retrieve the True-Client-IP or X-Forwarded-For headers directly from browser-side JavaScript. Only server-side code has access to incoming HTTP request headers.
To make the Akamai service work properly, you need to set up CDN settings correctly in both NetSuite and your DNS provider. Many DNS issues with the CDN are caused by incorrect configuration.

If your CDN or DNS settings aren't set up right, your site might have performance or availability problems. Only advanced users should make changes.
