EXPANSION MEANT “DNS WAS BECOMING MORE IMPORTANT TO US.”

“We had quite an aging platform for DNS,” says Paul Ellis, Network Manager, Tesco.com. Tesco is the UK’s largest grocery chain and one of the biggest in the world, with stores in 14 countries.

“DNS was becoming more and more important and we had the option of upgrading all our DNS platforms,” says Paul, “but that would not have given us the guaranteed uptime we required.” With online revenues continuing to grow in share, Paul’s team needed a more scalable and reliable DNS solution.

NEUSTAR ULTRADNS: SCALABILITY AND GUARANTEED UPTIME.

Switching to Neustar UltraDNS, whose global infrastructure has a presence on six continents, Tesco is no longer limited as it plans for more growth. “Our business is growing rapidly and we won’t have to put in more name servers,” says Paul. “DNS is one thing we don’t worry about.”

UltraDNS routes queries to the closest available network node, ensuring the quickest, most accurate DNS responses. Tesco also takes advantage of Neustar’s load balancing services to coordinate traffic among various data centers, plus handle email lookups from overseas offices.

Best of all, Tesco enjoys a 100% uptime guarantee. “There hasn’t been any downtime,” adds Paul. “The service is incredibly seamless, with no issues and no headaches.”

“WE KNOW THIS BETTER FOR OUR CUSTOMERS.”

Tesco also enjoys faster resolution times. “Latency has definitely improved for our customers,” says Paul. “We want them to have a good shopping experience and having a good response time is an important component.”

UltraDNS has also lowered operating costs, eliminating “several days per month of work” in DNS maintenance, as well as the hardware and software costs of in-house upgrade. Paul adds, “It is impossible to calculate the cost of a DDoS attack, but that figured into our decision.”

At the end of the day, “We know this is better for our customers. We are providing better service now.”
