DNS is one of the fundamental building blocks of internet applications and was high on the wish list of our customers for some time already. DNS is an absolutely critical piece of the internet infrastructure. There are two main types of DNS servers: authoritative servers and caching resolvers.

DNS, which stands for domain name system , is an Internet service that translates domains names into IP addresses. You can think of a DNS server as a phone book for the internet. Using a fast DNS hosting provider ensures there is less latency between the DNS lookup and TTFB. What is DNS? So DNS services definitely go down!

You’ve probably heard things like: “HTTP/3 is much faster than HTTP/2 when there is packet loss”, or “HTTP/3 connections have less latency and take less time to set up”, and probably “HTTP/3 can send data more quickly and can send more resources in parallel”. However, it is extremely challenging to actually deploy them at Internet scale.
