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!
