DNS change takes long time (nearly 2 weeks)
experiencing problems changing DNS information

Hi,
I'm experiencing a problem I've never had before. Whenever I changed any DNS info in the past, it has gone through in 24-48 hours (usually 24, never beyond 48). This time it took about 3-4 days before I saw any intention to switch over to the new DNS info. However, it never lasted more than about half a day before it reverted back to the original one and pointed to my old location. Since then it has been flicking back and forth a couple of times a day... with the exception for the last few days when it has consistently been pointing to my old location.

What should I do? What can I do?

I forgot to mention... it has now been 11 days since I changed DNS info with my domain host.

This happened to me recently - contact your web host and ask them to look into it.

It was some kind of error in my DNS zone (whatever the hell that is!)

consider using 3rd party dns (a dns company).

for some of my domains, I use a domain registrar's dns with no problems at all. for others, I use 3rd party dns with no problems.

I using my web host's dns... and I'm moving from one web host to another. I've moved some of my domains earlier with no problem at all. But not now...

Who should I approach? My web host or my domain host?

Web host fixed my problem

ok, this is the latest:

I realised that mydomain.com takes me to my old server while www.mydomain.com takes me to my new server (I'm not sure if this is a recent thing or if it has been like this all the time since DNS change). How strange is that... I spoke to my web host, and his only advice was to try to clear any cache, which I did. Problem is still there.

Have you ever experienced anything like this, or do you have an idea what it could be?

Must be a bug or some kind of error. Possibly the registrar is not submiting the DNS changes or doing it slowly.

Most of my nameserver changes take effect very fast. A few yrs ago it was often 24-hrs or so but we have had so called 'instant propogation' for a long time.

Recently (with some registars) I have seen delays of as much as roughly 6 to 12-hrs but even that is not common. As an example, I changed DNS yesterday on a .org domain which was parked to a new website on a different server which new site resolved in 2-minutes.

Depending on whose nameservers your domain name are supposed to use and
how they're configured, it might or might not have the same settings to have
the desired results. Both mydomain.com and www.mydomain.com should point
to the same place.

Since you said "domain host", ask them if both records for mydomain and www
are pointing to the same place where they're supposed to point to. They may
be able to fix that.

If you have spare time, search for "A records" and "CNAME records". They can
help you understand why this occurence.

The difference is that they are completely different domains.

You have to set up both. Setting up one does not automatically get you the other.

Well, with some hosts or registrars, it might in fact be the case that setting up one automatically sets up the other. But, technically - they are two separate DNS entries.

It follows, then, if you change one - you need to change both. Sounds like somebody didn't.

I see what you are saying about it being different domains... but in either case, typing in either www.mydomain.com or mydomain.com should take me to my web host (or?), something which is not the case at the moment. Typing in mydomain.com takes me to my old web host, while www.mydomain.com takes me to my new web host.

Typing in mydomain.com takes me to my old web host, while www.mydomain.com takes me to my new web host.

Apparently that's because the record for www.mydomain.com was updated, but the record for mydomain.com was not.

They are two separate DNS records. Each has to be updated.

Nothing but convention requires that they point to the same server.

Things are solved now. My web host said that:

domain name A record = IP adress
www CNAME = domain name

what he did was to remove CNAME and add an A record instead.

I'm not entirely sure what all this means (need to look it up...), but it seems to work.
