January 15, 2008 — (WEB HOST INDUSTRY REVIEW) — Windows-based hosting provider Server Intellect (www.serverintellect.com) has introduced high-availability geographically-redundant Domain Name System hosting for free to all customers, providing greater uptime, faster DNS response times and increased reliability.
According to the company’s announcement Wednesday, Microsoft gold partner Server Intellect has released free hosted DNS powered by a robust Anycast DNS system, enabling customers to host their DNS across multiple, redundant DNS Servers located in three enterprise-class data centers located in Seattle, Dallas and Washington DC.
Commonly used by large enterprise businesses, a geographically redundant DNS network is a powerful technique for providing redundancy and load sharing to specific types of network services on the Internet.
Simply put, the Anycast DNS system assigns multiple instances of an IP address to separate locations, and by using the underlying routing infrastructure of the Internet, data is forwarded to the nearest instance of an Anycast service. If the nearest routing center is down or experiencing unusually heavy traffic, another is automatically chosen resulting, preventing requests from being dropped.
Server Intellect’s Hosted DNS system offers customers the ability to configure enterprise-level DNS redundancy in real-time with a few quick clicks in the Server Intellect Unity Customer Portal.
“Service continuity is critical for businesses that operate on the web,” Server Intellect chief technical officer Adam Cady in a statement. “This new feature will provide another layer of network protection to customers who demand maximum uptime. Businesses can trust that Server Intellect is committed to helping their web ventures succeed, and I do feel this feature release is a reflection of that philosophy.”
