CDNsun Pricing

CDNsun’s pricing is based on a Pay as You Go basis. Therefore, there are no monthly commitments and you simply pay for the amount of CDN bandwidth you use. The cost per GB also decreases depending upon the amount of traffic you generate. However, with CDNsun there is no one single price per continent. Rather, the way they have structured their pricing is that the cost varies depending upon which specific PoP location your visitors are accessing. Therefore, although their base price starts at $0.045/GB in many of the US states, the price can go up to $0.159 for other regions such as Dubai or Brisbane.

CDNsun offers 6 different pricing levels which all include the same features, however vary in their price per GB as well as the number of websites you can accelerate.

CDNsun Review – In Conclusion

Overall, CDNsun has a fairly large network for being a relatively new competitor in the CDN market. They do also support many important features such as HTTP/2, real-time stats, origin push / pull, etc. Although, it is important to note that some of their features cost extra and if you want to add more zones to your account then you will be required to produce more traffic (minimum 2TB per month).

It should also be noted that if you have visitors from around the globe then you will be paying vastly different prices per GB of traffic. As mentioned in the pricing section, CDNsun’s pricing is based on the server location and can vary quite a bit from the base price of $0.045. Of course, if you are generating more traffic, you will benefit from reduced volume pricing however certain regions will continue to be considerably more expensive than US PoP server locations for example.

Hopefully, this CDNsun review has helped you in making a decision regarding whether or not CDNsun is the right CDN choice for you. Remember to be aware of where your visitors are coming from geographically before choosing a CDN provider in order to ensure that you aren’t charged high prices for bandwidth that you weren’t expecting.
