DESCRIPTION:Fast DNS resolvers are a crucial component in delivering a sna
 ppy internet experience for end-customers. If the resolvers are down or un
 der heavy load\, even the best internet connection is useless for most cus
 tomers.\nIn this talk I'll cover how to design and set up a scalable\, hig
 hly available DNS resolver infrastructure for internet service providers.
 \n- Anycast IPs using BGP for horizontal scaling and high-availability\n- 
 Health checks\n- Scaling nodes vertically to optimize cache ratios\n- Auto
 mation is key
