At its core, the Domain Name System (DNS) is the internet’s address book, translating human-friendly URLs into IP addresses. To ensure uninterrupted access and resilience, enter the Secondary Domain Name System service. Acting as a backup to the primary DNS, this service holds a mirror copy of the DNS records. In the event of primary DNS failures—whether due to technical glitches, high traffic, or malicious attacks—the secondary DNS seamlessly takes over, ensuring continuous website accessibility. By distributing the load and acting as a failsafe, a Backup DNS service not only enhances performance but also fortifies a site’s defense against downtime. In the digital age, it’s a safeguard every online entity should consider. Find a detailed guide on how you can boost your security with Secondary DNS.
