It appears that nowadays when I buy a new domain and link it to my host, it's unavailable for like 24 hours (with that default "parked"-type page). Then, it is suddenly accessible again. But only for like an hour, then it goes back to being "parked". I know this has something to do with DNS servers or something, but I never really understood it. And this is new, too. I used to buy a domain, apply the correct nameservers and almost instantly have access to working on it. Nowadays it takes like a week until it's stable. Is there anything I can do to speed this up?
This is very normal when you just update the name servers. But, this settles back to normal and the site shows up in 1-2 days.
It could be the place where you purchase your domain. Mine always work instantly. Btw, there is a Domain section you know.
