Major Rewrite and Speed Enhancements

26th December 2012

Today whatsmydns.net underwent a major rewrite - this includes a full rewrite of the design, database and core functionality of the DNS propagation checker as well as the blog, articles, and supporting pages.

These changes bring whatsmydns.net up to date with a responsive design which will provide a nicer experience for users who have larger screens.

The core DNS propagation check has also been rewritten to bring faster and more accurate results to users. Moving forward this will give more flexibility for future upgrades.

Amazon CloudFront CDN is now being used to provide static content from endpoints located all around the world - this will make loading the website much faster for international users.

Supporting content and pages such as the DNS server database and Flush DNS page have had caching implemented as well which will further speed up page load times.

Hope you all like the changes and we look forward to bringing you more updates in the future.

DNS Propagation Check for Malaysia, India and Pakistan

16th December 2012

whatsmydns.net continues to grow and add additional countries to the list for propagation checking - today we're announcing new checks for Malaysia, India and Pakistan.

Adding extra countries to the list that whatsmydns.net checks will provide greater coverage when determining if your DNS changes have propagated around the world.

In other news - while it may seem like this blog has not been updated in quite some time (2 years!) there has recently been quite a lot of work done on the site with the addition of moving over to Amazon Web Servies for added stability and reliability. We hope to bring you some exciting new features in the near future.

DNS Propagation Check for Germany and Turkey

9th November 2010

whatsmydns.net now provides DNS propagation results for an additional 2 countries - Germany and Turkey.

The addition of more countries to the system will allow users to more accurately monitor DNS propagation and identify any errors to their DNS configuration even faster. This will ultimately make the tool even more useful for users who are making changes to their domain names configuration.

The DNS servers for both of these countries have been kindly provided by the Offensive IP Database so make sure to check them out!

Advanced Link Sharing

10th March 2010

A great new feature has been added to whatsmydns.net today, it's a feature that I have been meaning to add for quite some time now but I received an email from a user a few days ago asking for more or less the exact feature I had in mind so I figured that many other people out there would benefit also so I decided it was time for it to be implemented.

whatsmydns.net now supports advanced linking so that you can more easily share links with your friends, coworkers, or people helping you out on a community forum or similar. The way it works is very simple and does not change the way that the site works in any way. There are 2 important changes to the site.

  1. Whenever you perform a search to check DNS propagation the fragment portion of the URL (the bit after the #) will be updated with your search query. This is the link that you will need to share with people.

  2. You can now access the site with the links that have been shared from the above step by simply going to the URL and when the page loads it will automatically perform the DNS propagation search specified in the link.

I hope that many people find this a great addition to the functionality of the site and that it helps out people when sharing links online to whatsmydns.net

What's My DNS Design Update

24th February 2010

whatsmydns.net has had a major design update today! Since the website started out it has more or less looked very much the same with the odd graphic change here and there along with a few different main header images.

whatsmydns.net has grown substantially since its initial release and now contains many more pages and therefore a design overhaul was needed. The changes made to the site should give the user a much nicer browsing experience both in terms of looks and navigation additions.

I hope that as the site continues to grow that I will be able to keep adding great features while maintaining a great overall look and feel.

Thanks to all those who have supported the site as its grown and I look forward to adding new features in the future.

DNS Checks for Red-Green Color Blind

5th September 2009

Just a quick update to the status markers used to show the state of DNS propagation on the main whatsmydns.net home page, these changes have been made due to the request of users who were having trouble distinguishing which DNS servers had propagated and which had not due to color blindness.

New DNS status markers:

Old DNS status markers:

I hope this change helps where it is needed, the feedback so far has been very good.

What's My DNS New Banner Image

1st September 2009

A little cosmetic update to the website today, as you may have noticed we have a brand new banner image across the top of each page on What's My DNS. This new banner shows at a glance what the website is about so that new visitors will quickly gain a better understanding of the service we offer - which of course is checking the current state of DNS propagation around the world. Of course on top of that it just looks much nicer than the old one so that's a bonus.

For reference purposes here is the old banner:
