MILESTONE ALERT: OpenDNS Handles More than 7 Billion DNS Requests While Providing 100 Percent Uptime

World's Largest, Fastest Growing DNS Service Answers Record Number of DNS Queries in 24-Hour Period

August 4, 2008; 06:08 AM

San Francisco -- OpenDNS, the award-winning navigation service that makes the Internet safer, faster, smarter and more reliable, today announced it has for the first time successfully answered more than 7 billion DNS queries in a single 24-hour period while providing 100 percent uptime. The announcement comes on the heels of the news that OpenDNS was one of only three DNS providers that are not now, nor were ever vulnerable to the major DNS cache poisoning threat found by security researcher Dan Kaminsky.

OpenDNS, which launched its service 24 months ago, has had unprecedented success in its quest to improve the Internet. With millions of users at tens of thousands of businesses, schools and households around the globe, OpenDNS is making the Internet safer, faster, smarter and more reliable than ever before.

"When we launched our service two years ago we were thrilled to successfully answer 1 billion DNS queries in our first month," said OpenDNS CEO David Ulevitch. "Today we celebrate answering 7 billion DNS queries in a single day. Our unprecedented growth is proof that people around the globe want a better Internet. Unbundling your DNS from your ISP-provided Internet connection and switching to OpenDNS is the absolute easiest way to achieve a safer, faster, smarter and more reliable Internet.”
