Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I updated at 2:00AM (Brazilian Time) Route 53 and GoDaddy DNS info for my server, trying to point the domain vitrina.cc to IP 184.72.238.163

I can access the site through the IP but through the domain name I can't.

I've done this before and it never took so long. Is there any specific or general reason a DNS propagation could take so long? Am I missing something?

Thanks in advance

Caching. Not to be too mean, but if you're asking this question you really need to buy and read DNS and BIND so that you have a clear picture of how DNS works in the wild... –  voretaq7 Aug 30 '13 at 15:02

Hi, @TheCleaner, Sorry, DNS newbie here. What does this mean exactly? –  Ricardo Pedroni Aug 30 '13 at 13:20
    
It means that vitrina.cc resolves to the IP you said you were changing it to according to Google's public DNS server. Same holds true using 4.2.2.2, so it looks like your changes have taken by now. –  TheCleaner Aug 30 '13 at 13:25
    
That's the problem - vitrina.cc is still unacessible from where I'm connecting (Curitiba - Brazil). Never heard of such a large propagation time. Any idea why? :( –  Ricardo Pedroni Aug 30 '13 at 13:29
    
What DNS server is having the stale data? You'd have to find out from them...the TTL might be long enough that they haven't cached it out yet and gotten the update. –  TheCleaner Aug 30 '13 at 13:31
    
AWS puts a default 172800 seconds TTL (48h). My concern is why some servers would update but not others. Testing DNSs through here (preshweb.co.uk/cgi-bin/…) show that many don't even detect stale data, apparently –  Ricardo Pedroni Aug 30 '13 at 13:35
