-
Authoritative DNS Server Absence
If the domain name is newly registered or the authoritative DNS servers for that domain are not properly configured, the DNS resolution process will fail. When a DNS server receives a request for a domain it doesn’t recognize, it will attempt to locate the authoritative DNS servers responsible for that domain. If these servers are unreachable or incorrectly set up, the query results in a “Domain Not Found” response. For example, a new website might become inaccessible immediately after registration if the DNS records are not correctly propagated across the internet.
-
DNS Propagation Delay
After changes to DNS records, a period of time is required for these updates to propagate across the global DNS infrastructure. During this propagation period, some DNS servers may still be referencing outdated information, leading to the “Domain Not Found” error for users whose requests are routed to these servers. This delay can affect access to websites and services immediately after changes to DNS settings. For instance, a website migrating to a new hosting provider might experience intermittent accessibility issues until the DNS records are fully updated.
