Two years ago, Amazon, Comcast, Twitter, and Netflix were effectively taken off the Internet for multiple hours by a DDoS attack, because they all relied on a single DNS provider — Dyn. Can it happen again? According to the 2018 ThousandEyes Global DNS Performance Report, 68 percent of the top 50 companies in the Fortune 500 and 72 percent of companies on the Financial Times Stock Exchange 100 are still at risk. Two years after the Dyn DDoS attack, you’d think digital companies would have learned their lesson, but apparently, that is not so.

The study found that many of the biggest companies on the planet,  as well as 44 percent of the top 25 SaaS providers, don’t have a fallback DNS server option. That means that a single outage or DDoS attack could completely take their company off the Internet. 

"Without DNS, there is no digital experience."

DNS is the “phone book of the Internet.” It’s the first step in how humans connect to online brands because it’s the Internet infrastructure that translates human-readable domain names to routable IP addresses. Without DNS, there is no digital experience. It’s the least appreciated aspect of delivering online user experience and the most overlooked chink in an enterprise’s armor. Even digitally mature organizations can get DNS wrong by not following the best practices around resiliency. It’s also a complex topic that most networking professionals haven’t spent enough time trying to understand.

Raising DNS Awareness

One of the goals of the report is to provide educational insights into how DNS works, its criticality, the nuances of how user choices, Internet infrastructure, and enterprise choices that all impact DNS performance and, thus, digital experience. The DNS expert community is select, but the need for awareness of DNS has grown as more businesses than ever rely on digital experiences in their revenue generation. According to Gartner, CIOs report that 37 percent of their revenue will have a digital footprint by 2020. If DNS is the first step in every digital experience, than not getting that step right can be incredibly costly.

As for the lack of enterprise DNS resiliency, consider this analogy. Most IT professionals would never consider building a data center without backup power or redundant telecom or Internet connections. Furthermore, most know that redundant connectivity isn’t truly redundant unless there is diversity amongst physical cable routes and facilities. But, too many are using a single DNS server. If that DNS “power” gets cut, it doesn’t matter how much you spend on your CDN or your regional cloud hosting. Your brand will be offline and scrambling. If we can help more organizations understand DNS and improve their architecture and their operational processes, then the report will have done its job.
