Centralized DNS for Faster, Safer and Easier Hosting

Looking back 2 years ago at our promise to unleash a series of service enhancements after switching fully to Site Tools, we keep delivering! After launching the Ultrafast PHP, new MySQL setup on shared and cloud, SG Optimizer new features, and more, we have also reworked our DNS service to make it faster, safer, more flexible and easy to use than ever. Take a read at what we have done and how that affects your websites hosted on our platform. 

What’s under the hood of our new DNS service 

Let us first make a quick reminder – the DNS (domain name system) is what makes it possible for a domain name to open a specific website. This system indicates on which of all the servers in the whole internet your website is hosted. Usually, a specific set of 2 nameservers and 2 IPs correspond to each server and they should be added in your domain’s management panel for the system to work. Each server also has a DNS service installed on it that processes the DNS queries and shows the proper website when a visitor types your domain in the browser. 

With our new centralized DNS setup we no longer need DNS service installed on each of our production servers that host your website. We are able to move all our DNS services to a completely separate cluster of multiple servers. This cluster is dedicated for DNS service only and is geographically dispersed around the globe thanks to the super cool Anycast network routing technology. Centralized DNS also allows us to have just one pair of nameservers and IPs for all the servers that SiteGround manages, and these are:

  • ns1.siteground.net
  • ns2.siteground.net

What are the benefits of our new DNS service

Faster Domain Resolving, Faster Website Loading

When a visitor searches for your website’s domain, the first thing that the browser does is make a DNS lookup to see on which IP the domain resolves and connects to the server with that IP. With the previous DNS setup lookup requests coming from a different continent from your server’s were handled a bit slower due to the physical distance between the visitor and the server resolving your domain. Now, with the centralized DNS which works on five different geographical locations and multiple instances, the resolving is handled by the closest node saving networking delays and improving your website loading speed.

Enhanced Redundancy 

As the new DNS setup relies on multiple geographically dispersed machines, it is extremely resilient. For example if one of the DNS servers goes down, the DNS requests would be handled by the second closest point, which is up and running. This setup also guards against DDoS attacks, as if there is a high amount of malicious traffic, it will be distributed among multiple DNS machines and it becomes much more difficult for such an attack to succeed. On top of that the DNS service is super scalable, and new machines can be added easily whenever there is a need for more resources.

If you are using your domain simultaneously for your hosting at SiteGround and other services too (for example your MX records are pointed to Gmail), having the DNS service hosted on a different location from your website has one more advantage. In case your hosting server goes down, your DNS will still work and your outside services will still resolve without being affected. 

Seamless Migrations Between Servers 

It’s part of our job to move data around – whether we transfer your account from an old hardware to a newer one, from cPanel server setup to machines with Site Tools setup, or from an old data center to Google Cloud infrastructure, migrations are something that happen and will continue to happen. Every time we migrate servers, one of the biggest challenges is handling the DNS zones. The new server comes with new nameservers and once websites get transferred, the domains have to be pointed to use the new nameservers. We have been updating them automatically for all domains managed via our control panels, but external domains needed manual change by webmasters. In both cases, there would be DNS propagation with potential downtime impact. With the new Centralized DNS it will be much easier to migrate and perform server upgrades in the future. In most of the cases such migrations would not involve any kind of DNS settings change thus preventing any issues caused by propagation. 

More Convenience & Ease of Use for you

With the decentralized DNS, people managing multiple sites on different servers have to keep track of different sets of nameservers, which may be inconvenient. The new centralized DNS simplifies multiple web site management processes for our clients, as all domains of all sites hosted on our platform, regardless of their hosting account or server can now use the same pair of nameservers.

When will the new DNS service become available?

All new websites created on our platform are already using the new DNS service. For older websites, we are now starting a gradual switch to the new centralized DNS. We will be updating nameservers for all domains registered with us automatically. For external domains used with our system, we will be informing our clients by email, confirming when it will be safe to update their DNS settings to the new ones. The old DNS system will continue to be supported for several more months, till the migration to the new one is fully completed.

My ping time result decreased from 28ms to 4ms when compared the old to the new. That's amazing! it seems DNS sitting very closed to visitors. I couldn't wait your news ready for migration. My little question concerning the new centralized DNS. Does it also to support new features like DNSSEC, IPv6 DNS records, and DNS records lengths longer than 1024 bits? I don't expect to see they will come out soon but only to stay tuned if you keep them in wish-list. Thank you.

So for webmasters that have hundreds of website hosted with you, on multiple types of accounts (both personal & client sites) what will we have to do to make sure there are no interruptions or website downtime? Candidly I'm getting tired of all these IP address and DNS changes you are making us go through! Last time you did a major change almost every single FTP had to be reconfigured. Sometime you people are a nightmare!

You don't need to change IPs. We had to do these when we migrated our entire infrastructure to GCP but that's not something we do often really. If you have domains pointed via A records, you don't need to do anything on your end.

I am wondering if this decentralized DNS system will reduce the severe latency of the new Site Tools management platform. The old cPanel system worked great for me, but when you migrated to Site Tools, everything slowed to a crawl. I have had to get used to waiting up to 10 seconds after keystrokes and mouse clicks before anything happens. I also miss the old WYSIWYG editor.

This all seems great stuff and fits with your commitment to making your customers websites load faster and helping keep things secure and running reliably as well. However one thing that really grinds my gears about SiteGround is because I am British and speak English 'English'. I hate the way your websites uses American spelling for words like centralised and optimised even my web browser and computer operating System , both of which are developed by organisations based in the USA, know how to speak and spell the 'Queen's English' . However running a Global Web Hosting business is just like politics you can never please all of the people all of the time. Keep up the good work 😁

There shouldn't be any impact for CDN users, what matters is whether your website traffic is pointed to your SiteGround hosting via DNS records (IP) or via name servers. (In the first case, no changes are needed. In the latter, please ensure that the name servers in use match the ones displayed in SiteTools.)

I have all my domain registered with NameCheap and use the name severs given to me when I set up each site. So you will email me when I need to change the name servers correct and then I will change them to: -ns1.siteground.net (75.2.77.104) -ns2.siteground.net (99.83.229.113) Is this correct? Do you know when will this will all happen? Also, will there by any down time to our sites when we change the name severs to the new nameservers?

DNS is the obligatory connection between your domain name registration and the webserver on which your website files are located. Cloudflare is an additional CDN (content-delivery-network) service that some people use. There are various DNS setups, which is why there cannot be a unified configuration tutorial. Still, if you reach our Support via the HelpCenter flow in your ClientArea, our techs will be able to offer guidelines tailored to your personal needs.

1. So if a client has their domain at some host like GoDaddy and they use nameservers to point (not A records) does this mean their site AND email will be impacted until nameservers are updated at GoDaddy? 2. Most of our clients are not on a maintenance plan with us and will have no idea how to update their nameservers. Will collaborators on Siteground accounts be emailed the notification along with the site owners? That would be helpful. Thanks

May I offer a bit of feedback for regarding the email "New DNS service for your site(s) now active"? One part of the Instructions section is very, very confusing. One paragraph says: “For domain names pointing through A record …” do nothing. The very next paragraph says: “For domain names, NOT registered by SiteGround ..." do something. But my domain name meets BOTH criteria. So which instruction was I supposed to follow? I called the Help Desk and they told me I didn’t need to change anything. It would have been so much clearer if the relevant paragraph had started: “For domain names, NOT registered by SiteGround but using SiteGround's nameservers ..." and the instruction had been to “update the nameservers to the new ones”.
