How DNS Propagation Works: Why Your Website is Still Down

The Address Book of the Internet

Computers don't understand amanaflow.com. They only understand IP addresses like 192.168.1.50. The Domain Name System (DNS) translates human-readable domain names into machine-readable IP addresses.

When you purchase a new web hosting plan and change your domain's Nameservers from GoDaddy to AmanaFlow, you are essentially telling the internet: "Whenever someone asks for my website, ask AmanaFlow's server for the IP address."

Why Does Propagation Take 4 to 24 Hours?

The internet relies heavily on caching to remain fast. If your local Internet Service Provider (like Comcast or BT) had to ask the central root servers for an IP address every single time a user visited Facebook, the internet would collapse.

Instead, your ISP saves (caches) the IP address of Facebook. When you update your Nameservers, your local ISP doesn't know about it instantly because they are still looking at their cached, outdated version of your domain.

Time to Live (TTL) Explained

Every DNS record has a TTL value (usually measured in seconds). A TTL of 14400 means 4 hours. This tells ISPs: "Keep this IP address cached for 4 hours before checking back with the authoritative server to see if it changed."

If you know you are migrating a website on Friday, change your TTL to 300 (5 minutes) on Wednesday. When Friday arrives, ISPs will update your new IP address almost instantly.

How to Check Your Propagation Status

Do not clear your browser cache repeatedly; it won't force your ISP to update. Instead, use a global DNS checker tool like whatsmydns.net.

1. Enter your domain name.
2. Select NS (Nameserver) or A (A-Record).
3. Click Search.

You will see a map of the world. Green ticks mean that specific geographic region has updated to your new server. Red crosses mean they are still looking at the old cache.

FAQs

Q: Can I access my website before DNS propagates?
A: Yes! AmanaFlow provides a temporary control panel URL (e.g., http://192.168.1.50/~username) so you can build your WordPress site while waiting for the domain to propagate globally.
