Global Coverage

CDN Pro’s global network covers the most significant areas on the planet and continues to expand the reach of its global network. Its points of presence (PoPs) are organized into “server groups” with a different price for traffic served from each group. You can choose which server groups to use for each country and ISP, allowing you to fully customize performance and cost based on your budget.

About Server Groups

When selecting a server group for the first time, we recommend that you create client zone rules that use the Standard server group, and then change to another server group if needed later.

If you create a client zone rule and select Premium, Deluxe, or Ultra, all the lower priced groups will be included automatically and can be used to deliver content. For example, if you live in North America and want the best possible performance for your users, regardless of cost, choose Ultra.

When a user requests your content, the CDN Pro load balancer makes an intelligent routing decision based on the user’s location and current network traffic, and then chooses an appropriate server to handle the request. The server that handles this request is located at any of the CDN Pro PoPs around the world and might be one listed as Standard, Premium, Deluxe, or Ultra. Traffic used by different server groups is reflected in the Traffic Volume Summary report as well as in monthly invoices.

Note: CDN Pro also supports the following special server groups for customers with China access enabled: nearChina, ChinaStandard, and ChinaPremium. For more information, contact the CDN Pro support team.

Example

Assume your main objective is to ensure the performance of your website in Japan and Korea. In this scenario, you may want to configure the edge hostname to use all server groups outside China to serve these two countries while using the “standard” group to serve the rest of the world. The screenshot below shows the completed configuration on the portal.

Frequently Asked Questions

A:Is there any difference between PoPs in different server groups?

For consistency, server hardware is largely the same across server groups. The main difference between different server groups is the bandwidth cost charged by our vendors (ISPs). A PoP in the “ultra” group is more expensive than one in the “standard” group, but does not necessarily deliver better performance than a “standard” PoP. Performance experienced by each end user is determined by the connectivity between the user and the PoP. Adding the “ultra” group to serve a region just provides our GSLB algorithm more PoPs to choose from, such that the end users in that region are more likely to get a PoP with better connectivity.

A:If I choose to use the Ultra server group for a region, will all traffic in that region be charged the Ultra price?

No. The CDN Pro GSLB assigns PoPs primarily based on performance. Adding “ultra” to serve a region enables the GSLB to choose from a larger pool of PoPs for that region. If the algorithm determines that a request will be better served by a “standard” PoP, the traffic is still served from that PoP and incurs a “standard” charge.

A:Are there performance guidelines for server groups that cover certain regions?

In general, the “Standard” group delivers excellent coverage for North America , Europe, and some regions in Asia. Adding the “Premium” group can enhance the performance in those areas as well as the Middle East. Adding “Deluxe” delivers good performance in APAC countries. Adding “Ultra” gives you our best possible performance in all areas including South America, Oceania and Africa. We invite you to try different configurations to determine the right balance between performance and cost.
