Which DNS record does which job, why the root domain needs special handling, and three setups site owners actually meet.

DNS propagation is not a wave spreading across the internet but caches expiring one by one, and TTL decides how long that takes.

A CDN adds a cache-and-protection layer in front of a blog, so the real question is whether delivery or the server is slow.

Unlock the domain, get the auth code, start at the new registrar, and keep DNS running while ICANN's transfer rules do the rest.

A security warning on your site can mean a wrong name, an expired certificate or plain http images, and each has a different fix.
