Domains, DNS & SSL
These systems are invisible when they work and suddenly very visible when they do not. Here is the business-owner version without turning it into a network engineering lecture.
DOMAIN
Your domain is the human-readable address people type, such as launchday.digital. Registering the domain does not automatically create or host the website.
DNS
DNS is the routing layer. Its records tell browsers, email providers, and other services where the domain should go. A wrong DNS change can affect the website, email, or both.
HOSTING
Hosting is where the production application or website runs. The domain reaches that environment through DNS.
SSL / HTTPS
SSL certificates allow encrypted HTTPS connections. Modern hosting platforms often automate certificates, but the domain still has to resolve correctly before the certificate can be issued.
ROOT + WWW
example.com and www.example.com are technically different hostnames. Decide which one is primary and redirect the other so users and search engines see one canonical version.
EMAIL RECORDS
MX, SPF, DKIM, and DMARC records affect business email and transactional email. Website migrations should avoid touching these casually.
PROPAGATION
DNS updates are distributed through caches. Some changes appear almost immediately while others take longer to be seen everywhere.
OWNERSHIP
Keep the domain registered in an account the business controls. Document who manages DNS, hosting, email, and renewals so ownership does not disappear with a vendor.
The site is not finished until people can reliably reach it.
Launch Day handles the production layer alongside the design and build.
We can configure the domain, DNS, SSL, hosting, redirects, forms, and production QA.
