DNS propagation occurs whenever any part of your domain's DNS has been modified or updated. DNS changes are not always instant - they can take up to 48 hours before the changes are reflected on your network. This wait period is called DNS propagation. Your website or DNS changes may not be online until the propagation period has passed.
How long does DNS propagation take?
The age-old rule is that DNS propagation can take "24-48 hours". However, it usually is much quicker than that - and we've seen that it usually can be resolved in as little as 15 minutes. The exact time it takes will vary depending on your ISP, your router, your computer, and your operating system.
Speeding up DNS propagation
You can speed up DNS propagation by clearing your DNS cache. You can find a guide on how to do that on Windows and Mac systems here:
It's also recommended to clear your browser cache in addition to clearing your DNS cache.
Checking nameserver status
You can look up your website's currently propagated nameservers with a tool such as https://intodns.com/
After searching your domain, refer to the "Domain NS Records" field. The reported nameservers should match the nameservers given to your account.
Checking root A record status
If you've recently updated your domain's nameservers, you will need to wait for DNS propagation before the changes take effect. You can check DNS propagation status on your root A record with a tool such as this one: https://www.whatsmydns.net/
Begin by entering your domain into the text field, and click "Search". This will perform a lookup of what IP address your domain is reporting across the globe. If an "X" is displayed in many locations, then the propagation hasn't completed yet.
If an IP address is reported, then you should look up the IP address to ensure it's the correct IP address. Your server's IP address is mentioned in your welcome email, but another easy way to check it is by looking up the IP address on a website such as https://ipalyzer.com/
With Ipalyzer, you can search the IP address and read information about the IP address. When searching an Arch Hosting IP address, you will see that the "RDNS" field under the "Info" tab says your server hostname. If you look up an IP address obtained at whatsmydns.net and then ipalyzer.com confirms that the RDNS matches your server, then chances are the site is configured correctly for those locations.
