In order to transfer server and domain management
First, we changed the registrar.

And I switched DNS earlier, but the website got an IP address error
Mail can only be sent and not received.

Errors on the browser
I cannot access this site. The server IP address for xxx.com was not found.
Is displayed.

Also considered as the DNS penetration period
I returned DNS after a while and tried to access the old server with the same result.

Are there any solutions?

  • Answer # 1

    If you can't dig, you might have missed the A record or accidentally changed the name server
    Calm and review is the fastest solution

    Generally, the TTL is shortened beforehand when switching
    Because it is easier to switch back

  • Answer # 2

    The DNS penetration problem is an urban legend-explaining the correct server moving method

    However, when that happens, I think we have no choice but to wait
