Can’t we all just get along: July 6th Cloudflare/Dyn DNS Issues


Today, shortly after 5PM EST, a large portion of the internet suffered an outage which also impacted us here at AddThis. Two major internet services, CloudFlare and Dyn, had trouble communicating. Dyn tells the world how to translate domain names, like, into addresses that computers understand and CloudFlare acts as a delivery network for content on the web. When these two services stopped talking to each other, a large portion of the internet went down with it. Our team, through our automated error detection systems, discovered this issue shortly after it began. Once we determined that the issue was not going to resolve itself quickly we made the decision to cut our traffic over to our secondary CDN provider. This move stabilized our systems and reduced the outage period for us and our customers. At this point everything is 100% back to normal.

The internet is a complicated environment that requires countless systems to work together in order to function properly. Visitors to your site don’t really care about that, they just want your site to load quickly and without error.

No one takes uptime more seriously than we do and while these incidents are unfortunate please know that we are on the case and will do what it takes to correct the problem.
