DNS downtime refers to the period of time when the Domain Name System (DNS) is unavailable, resulting in the failure to resolve domain names to their respective IP addresses. This can happen due to various reasons, such as network outages, server failures, and cyberattacks. During DNS downtime, websites, and online services become inaccessible, leading to a loss of revenue, decreased user satisfaction, and reputational damage. Therefore, it is crucial for businesses to monitor their DNS performance and have a backup plan in place to mitigate the impact of downtime. Learn more about DNS downtime!
DNS resolution – Definition
DNS resolution is the process of converting a human-readable domain name into an IP address that machines can understand. When you type a website’s domain name into your browser, your computer sends a DNS query to a DNS server to retrieve the corresponding IP address. This lets your computer connect to the website’s server and load its content. DNS resolution is a crucial component of the internet’s infrastructure, and without it, we would need to remember a long string of numbers to access every website we visit.

What does the DNS cache represent?
The DNS cache is a temporary storage of Domain Name System (DNS) data on a device or server. It helps to speed up the retrieval of DNS information and reduce network traffic. When a device requests a domain name, the DNS server checks if the information is already in its cache. If it is, the server sends it back to the device without having to perform a full DNS lookup. This process is much faster and more efficient than retrieving the information from scratch. Read more about DNS cache!
Anycast DNS – briefly explained
Anycast DNS is a type of Domain Name System (DNS) service that allows the same domain name to be served by multiple servers located in different geographic locations. When a user queries a domain name, the request is routed to the closest server in terms of network distance, improving the speed and reliability of the DNS resolution process. Anycast DNS is commonly used by Content Delivery Networks (CDNs) and other large-scale internet services to improve their performance and uptime. Check out additional information about Anycast DNS!
