Learn how an online reporting company leveraged the UltraDNS global network to guarantee superior site performance to its 4 million plus users
Introduction
The company's Web site provides research tools and up-to-date pricing on thousands of new and used vehicles, including the company's industry-standard New Car Valuation Service, which reveals what a new car is actually selling for. Car buyers and sellers have relied upon online information for authoritative and unbiased information to make well-informed automotive decisions. The company reports vehicle prices and values via products and services, software and Internet site. Its web site has been rated the No. 1 automotive information site by Nielsen//NetRatings as well as No. 1 and first visited automotive site by J.D. Power and Associates six years running. It attracts over 4 million unique visitors each month and produced more than 28 million pricing reports for consumers.
Enterprise Challenges
The company was managing two DNS servers co-located on the east coast and the west coast running BIND software. It was concerned with the reliability and the performance of its DNS infrastructure andneeded a solution that would increase the speed of resolution and eliminate failures that prevented their online customers from getting to their site.
The UltraDNS Solution
- The customer benefited from our global network. Instead of relying on an individual nameserver to respond to DNS queries with limited peering and connectivity, they upgraded to the UltraDNS global mesh of DNS servers collocated at multiple carrier-class Tier I backbone providers and secured in multiple co-location facilities.
- Improved site performance was derived from the UltraDNS IP Anycast technology. When applied to DNS queries, user requests were automatically routed to the closest topological UltraDNS node, reducing transit time network latency for DNS transactions
- Anycast reduces the number of queries that are routed to distant servers, which reduces the likelihood of encountering congested routers, thus reducing the number of query packets that are dropped and cause a DNS timeout/retry
Benefits
By adopting the UltraDNS Managed DNS Service, the customer was able to leverage the UltraDNS network, which is both reliable and extensive, without any additional IT investments. By using our scalable managed service, the company was able to improve their website performance and increased their user base by 3%.
