Announcing New Features To Help Hosting Providers Run Their Own Reliable DNS Infrastructure

On October 6th, 2016, Cloudflare announced the expansion of its Virtual DNS offering with two new features for enhanced reliability: Serve Stale and DNS Rate Limiting. The company has developed the necessary tooling, infrastructure, and expertise to handle large-scale DNS networks over the past six years. Virtual DNS serves as a protective layer in front of an organization's DNS infrastructure, mitigating DDoS attacks and providing a strong caching system across 100 global data centers. Serve Stale allows Virtual DNS to answer queries on behalf of an organization when their nameservers are down by serving stale answers from cache. DNS Rate Limiting helps control the traffic hitting an organization's network, allowing them to configure a threshold for the number of queries per second that Virtual DNS should send through to their DNS servers. These features aim to provide additional layers of reliability and protection for organizations running DNS infrastructure.
