Standard Presentation
Cloudflare hosts managed DNS infrastructure for over 5 million zones. In 2016 we began work on re-building a core part of our DNS Nameserver (rrDNS) and data provisioning software to better handle the scale as well as to improve reliability and performance, and pave the way for new features. DNS operations and systems are not immune from scaling bumps; things that work great for 100K domains...

Public Workshop
Standard Presentation
I would like to study and present the effect of parent (TLD) zone TTL changes based on behavior of different DNS resolvers implementations and how they handle the delegation NS TTLs. The presentation will include different scenarios where TTL matter, might matter, might not matter, or doesn't matter at all related to the DNS resolver implementations.
