We choose to to use Cloudflare as our CDN DNS service. What is a CDN DNS? Basically it is a great way to secure and distribute content across area specific servers reducing your own server load, bandwidth and potential for denial of service attacks. Cloudflare has data centers in Portland, Oregon so our locally based clients will benefit as will end users near any of Cloudflare’s world wide data centers. Cloudflare works at the DNS level so you set your name servers at the host level and Cloudflare takes over caching and speeding up your website. If you use WordPress to power your website we give you control of your caching from your WordPress dashboard.
