The most effective way to ensure uptime is to use multiple DNS providers. Think of it as adding a supplementary network to help handle your traffic.

DNS Made Easy releases a new study that calls attention to the dozens of retail domains still vulnerable to single DNS provider outages. Last month, a major DNS provider was attacked and many of its client’s domains were unavailable for hours on the US East Coast. The event was a wake-up call for enterprises and administrators still using only one DNS provider. As the holiday season approaches, DNS Made Easy is encouraging online retailers to use more than one DNS provider to ensure total availability during peak shopping days.

DNS Made Easy researchers looked at the top 100 retail domains according to Alexa, and found how many DNS providers each domain was using. Sixty-five percent of the top domains were outsourcing their DNS to a single provider. The researchers were shocked to see so many domains still vulnerable to single DNS provider attacks; even after the crippling effects of the East Coast outage and the holiday season around the corner.

The DNS Made Easy research team conducted a similar study days after the attack, but on the top 100 worldwide domains. The results showed that some domains that previously only used the downed provider had already added a secondary DNS provider. A week after the study, researchers found that even more domains (from many different providers) had added additional providers to their DNS configurations.

While there are so many assets that contribute to a website’s performance and availability, DNS is the most critical. That’s because DNS is the ingress point that decides whether or not a website will be available or not, before most other assets can even load.

“The most effective way to ensure uptime is to use multiple DNS providers. Think of it as adding a supplementary network to help handle your traffic,” says President of DNS Made Easy Steven Job. Secondary DNS works by distributing a domain’s query traffic between two or more providers. If a DNS provider becomes unavailable, the domain’s query traffic is automatically served by the available DNS provider(s) with virtually no effects to end-users.
