Delay in DNS Propagation right after name servers have been changed?

Is it my imagination but looks as though it is taking much longer than before for DNS to propagate after the domain name servers have been changed.

I noticed this when I recently purchased domains from Namecheap.com. It used to say that it can take up to 24 hours for the DNS to change, but it now says it can take up to 48 hours.

And it did take 48 hours.

Previously it would propagate almost instantly. Wonder what's up?

I'm also puzzled. What determines the speed with which a domain DNS propagates? The Registrar of the domain, i.e. Namecheap, or the Web host to which the name servers are pointed, or half and half? Ironically I also find change in browser catching up with the DNS. Like once Internet Explorer was quicker. Firefox took some extra time to get rid of cookies and flush DNS.

That sounds like a caching issue on your ISP possibly. I also get it sometimes, however if I try from a different ISP or mobile network provider it generally works.

48 hours far too long in my opinion though! That's 2006

Aha. Just Googled it and found this nice tool - will be using this next time.

As another challenge of course is when one gets impatient and check with one's browser, one's browser develops cache of "not found".

The link below should help for that.

I always manually enter Google's public DNS servers in every device and connection I have. There are a few other very good public nameservers. When I change DNS records, they usually take longer, but when I register a new CNAME or @ record, it's almost instant. Most of the time. haha

It's been a while since I created this thread, and must say that was temporary for me. Name servers are propagating very fast, like almost instantly these days.

Most times it is your ISP DNS servers that do the propagating. I usually change my DNS servers (which I have a tutorial on) to Googles DNS (8.8.8.8 and 8.8.4.4), OpenDNS (208.67.222.222 and 208.67.220.220), or another good one is Level3 (4.2.2.1, 4.2.2.2, 4.2.2.3)

OpenDNS also offer free filtering on their DNS servers. From porn, weapons, datingsites, phishing sites to malware sites, even viruses coming through the web it blocks. Obviously it can not block everything but does a really good job.

Aha! So kudos then to my ISP. :good:

In addition of course Freenom Registrar Website is very easy to manage. Like it takes me almost seconds to register a domain. Wish Namecheap and particularly GoDaddy could be that fast too. With the latter two I always seem to be looking for things, whereas at Freenom they seem to be in the right places.

I have had Namecheap for several years and only one time it did that to me. Very interesting to say the least.

Code: 
1.2.3.4 ? ? ? ?myfirsttestingexample.com
5.6.7.8 ? ? ? ?mysecondtestingexample.com

/etc/hosts has an alternative on windows machines too, just google it.
