DNS Flag Day: Will Your Website Survive?

What is the DNS Flag Day? The Domain Name System (DNS) was born in the 1980s and the first DNS Extension Protocol Specification (EDNS) was developed in 1990. Although the specifications were formulated nearly 30 years ago, some hosts still do not support the EDNS protocol, which has caused other hosts to make additional countermeasures for this, slowing down the DNS speed and limiting the new features of the DNS. For this reason, DNS vendors and large public DNS service providers will delete these old processes on the “DNS Flag Day” day.
