DNS downtime: Meaning
A DNS outage, also known as DNS downtime, is when the DNS is not functioning correctly. This implies that the IP address won’t be visible if you look for the domain name. Users will instead utilize DNS requests to find your domain. The domain’s authoritative nameserver will be requested by the DNS recursive server, but it will not respond and instead receive an error message.

That is, they convert the written file into numbers that machines can interpret.
