Routing around single point of failure DNS issues

Today's major attack on Dyn's DNS servers caused many popular websites to be down. As a developer, it is crucial to have strategies in place to work around such issues. Ably, a data stream network, has implemented several fallback strategies to ensure availability and reduce single points of failure. These include operating two primary endpoints with different domain registries, using separate DNS providers for each domain, having no reliance on a single datacenter, and having a distributed denial of service strategy in place. By addressing these potential vulnerabilities, Ably ensures that its customers can rely on their services to be up 100% of the time.
