Long-time Slashdot reader syn3rg quotes the DNS Flag Day page: The current DNS is unnecessarily slow and suffers from inability to deploy new features. To remediate these problems, vendors of Dns Software and also big public DNS providers are going to remove certain workarounds on February 1st, 2019. This change affects only sites which operate software which is not following published standards. Are you affected? The site includes a form where site owners can test their domain -- it supplies a helpful technical report about any issues encountered -- as well as suggestions for operators of DNS servers and DNS resolvers, researchers, and Dns Software Developers. The Internet Systems Consortium blog also has a list of the event's supporters, which include Google, Facebook, Cisco, and Cloudflare, along with some history. "Extension Mechanisms for DNS were specified in 1999, with a minor update in 2013, establishing the 'rules of the road' for responding to queries with EDNS options or flags. Despite this, some implementations continue to violate the rules. "DNS software developers have tried to solve the problems with the interoperability of the DNS protocol and especially its EDNS extension by various workarounds for non-standard behaviors... These workarounds excessively complicate DNS software and are now also negatively impacting the DNS as a whole. The most obvious problems caused by these workarounds are slower responses to DNS queries and the difficulty of deploying new DNS protocol features. Some of these new features (e.g. DNS Cookies) would help reduce DDoS attacks based on DNS protocol abuse.... "Our goal is a reliable and properly functioning DNS that cannot be easily attacked."
