Yesterday, the DNS servers of, one of Italy’s largest ISPs, went down for several hours. People who rely on for their Internet waited. And waited. And then waited some more for their Internet to come back. Outages like these highlight the importance of a reliable DNS service; when it’s working, you don’t think much about it, but when it’s down, essentially so is your ability to access the Web.

As with similar outages in the past, like ones experienced in Germany and by Time Warner customers in 2008, users of OpenDNS didn’t notice any downtime at all. In fact, in all four plus years we’ve been around, OpenDNS has a perfect, 100 percent uptime record.

Because of the outage, we experienced a surge in traffic from Italy — not surprising, since word spread via Twitter and other methods that using OpenDNS was one of the only ways to regain access to the Web. We’d like to take the opportunity to welcome our new Italian users — benvenuto! We’re happy you’re here, and look forward to helping you enjoy a safer, faster, smarter and more reliable Internet.
