CDNs can improve website performance, but they can also be very expensive, overly complicated to set up or insecure. We have found that OpenDNS is so far the simplest, most affordable alternative to conventional CDNs.
Faster, safer Internet with OpenDNS
"OpenDNS runs a really big, smart cache, so every OpenDNS user benefits from the activities of the broader OpenDNS user base," says Allison Rhodes, community manager of OpenDNS I tested that claim from my home base in India. After switching to OpenDNS, content-laden Web sites like news.com, cnn.com, bbcworld.com, and myspace.com loaded a lot more quickly, ping times were considerably lower, and query response times (measured with dig -x site ) to news.com, lxer.com, osnews.com, distrowatch.org, and bbcworld.com were lower by 10 to 25% compared to times when I was using my ISP's DNS.
