How can your company continue to make its website and Internet services available during a massive distributed denial-of-service (DDoS) attack against a DNS hosting provider? In light of last Friday’s attack on Dyn’s DNS infrastructure, many people are asking this question.
One potential solution is to look at using multiple DNS providers for hosting your DNS records. The challenge with Friday’s attack was that so many of the affected companies – Twitter, Github, Spotify, Etsy, SoundCloud and many more – were using ONLY one provider for DNS services. When that DNS provider, Dyn, Inc, then came under attack, people couldn’t get to the servers running those services. It was a single point of failure.
