GeoDNS: How to start using it?

So you want to start using GeoDNS. Congrats! That means your business is growing or already big.

Step 0. Know what GeoDNS is?

A Geographical Domain Name System or GeoDNS is a method to distribute the traffic considering the location where the DNS query was generated. GeoDNS involves a network of name servers located in strategic points of the planet. These servers have different IP addresses for the same domain based on the region or area they cover, and that represents an incredible speed boost for the DNS resolution.

The trick of GeoDNS is that it redirects the traffic based on the DNS clients’ IP addresses.

How to start using GeoDNS?

Step 1. Check your needs

Consider the real needs of your business. Analyze if you need such a network of multiple servers worldwide working for you. What’s your market? Do you have an international company or a very local one? GeoDNS is a great option for most businesses because it brings many benefits, like speed, efficient traffic distribution, IP filtering, quicker loading time, constant uptime, and redundancy!

But mostly, international companies use it because they receive a high volume of DNS queries 24/7 from clients around the world. Since the queries are produced in very different and far away locations, deploying GeoDNS makes total sense.

Step 2. Research DNS providers

Research different GeoDNS providers. Look for a quality and trustable service. And check that the locations it offers (network) are convenient to cover your specific market needs.

Step 3. Analyze the DNS plans

Analyze the different available plans of that provider. Don’t pay more for extras you don’t need. Calculate the number of DNS queries you expect to be sure the plan will cover your needs. Read carefully all the policies for payment, contract cancellation, technical support, the fine print, etc., not to be surprised.

Step 4. Configure your network

Once you get the service, your provider will run the GeoDNS, but you have to configure it on your system. You just need to add an IP address to every server in the world you choose to be close to your clients. It is easy. Just be careful while typing the IP addresses.

Step 5. Test

Run a test. Usually, the interface of most providers includes a tool to test (like Ping) what you configure and the changes you make. Test that the servers respond to the IP address you added to them.

Step 6. Your system is ready to start using GeoDNS

Wondering what will happen next? Well, when a user sends a DNS query to visit your domain, the DNS resolution process will be triggered, but this time, GeoDNS will make a big difference. The DNS server will read the IP address of the users to get their locations. Then, their queries will be sent to the nearest server to be processed. The answer to them will be quick, and the loading time will be reduced considerably.

Conclusion

GeoDNS is a great technology! If your company is steadily growing, already international, or if it is on the way to reaching that level, start using it today and enjoy its multiple benefits.

DNS outage – Everything you need to know

Imagine you have been preparing for months for the special sale of your e-shop. Clients impatiently wait for the countdown to point out the beginning. And when they all try to access your website, your domain name can’t be loaded. Clients receive an error message on every try. Yes, pretty sure your e-shop is experiencing a DNS outage.

And the issue is that this can make your clients angry or disappointed. You will lose money, and your reputation can be affected.

Better be prepared and know more about DNS outages. Here you have everything you need to know. Including how to prevent them!

What’s a DNS outage?

DNS outage or DNS downtime, as it’s also called, is a time interval during which a domain name can’t be resolved to its IP address.

The Domain Name System (DNS) and its resolution process are essential for accessing any domain name. If there’s a failure causing the DNS not to work, the necessary translation from domain name to IP address won’t happen. So the domain won’t be located, and therefore, its content won’t be accessible to visitors.

What causes a DNS outage?

A DNS outage can happen due to different causes:

  • Human errors. Yes, humans are behind a large number of DNS outages. For example, a script error, a misconfiguration, or a single typo on the IP address of the domain name can cause a DNS failure.
  • DDoS attacks. If the traffic overloads sent by attackers make your DNS servers crash, the domain name will be down.
  • Lack of redundancy. Of course, you can run your domain name with only an authoritative server, but it can be risky. Software or hardware failures, updates, regular maintenance, or a cyber attack can shut it down.
  • Propagation delays. Online businesses must delete, edit, or add different DNS records regularly. Propagating these modifications or updates across a complete network can take time. Technically, this is not an error or a cause of a DNS outage, but visitors who can’t reach your domain will perceive it like that. Once the DNS propagation gets completed, everything will be ok.

How to prevent a DNS outage?

Look for redundancy

Redundancy is key! You can use Secondary DNS services. Using multiple Secondary DNS servers, you can set them as Secondary authoritative nameservers. In case the Primary gets attacked or suffers downtime, the Secondary servers will answer the DNS requests of your clients.

Use DNS failover

This technology can automatically redirect traffic to a different server. In case of a server’s failure, DNS failover will get activated for the DNS resolution process to keep going. So your website will be accessible even if a server falls.

DNS load balancing

Load balancing is a great practice to avoid a DNS outage. While distributing traffic through the available servers, it can handle traffic spikes and prevent servers from being overloaded.

Conclusion

Preventing DNS outages on your online business is possible! Take action now! Don’t let it stop your operation.
