Internet has over 196 mn domain names

2010-09-23T20:14:00.000-07:00

The global base of Internet domain names grew by more than 3 million in the second quarter of 2010, according to the latest Domain Name Industry Brief, published by VeriSign Inc, a provider of Internet infrastructure services for the networked world.

The domain name industry ended the second quarter of 2010 with a base of more than 196.3 million domain name registrations across all of the Top Level Domain Names (TLDs). The second quarter total represents an increase of two percent over the first quarter of 2010. Compared to the second quarter of 2009, registrations grew by 12.3 million, or seven percent, across the industry, said the report.

The combined base of .com and .net domain names surpassed 100 million, finishing the quarter with an adjusted zone size of 101.5 million. New .com and .net registrations totaled 7.9 million during the second quarter, an increase of 13 percent from a year ago. The .com/.net renewal rate for the second quarter was 73.2 percent, up from 72.1 percent for the first quarter.1.

VeriSign's average daily Domain Name System (DNS) query load during second quarter 2010 was 62.5 billion per day, with a peak of 83.6 billion. Compared to first quarter 2010, the daily query average increased 16 percent and the peak grew by 32 percent. Taken annually, the daily average increased 28 percent and the peak daily queries grew 43 percent, the company said in a press release.

The latest domain name industry brief also spotlights the industry's progress in implementing DNS Security Extensions (DNSSEC), which is designed to protect users against 'DNS cache poisoning' and 'man-in-the-middle' attacks by cryptographically signing DNS data. In July, VeriSign joined with U.S. Department of Commerce and the Internet Corporation for Assigned Names and Numbers (ICANN) to deploy DNSSEC at the root of the DNS.

A new Forrester Research study conducted on behalf of VeriSign showed how timely the implementation of DNSSEC is. For the study, titled DNSSEC Ready for Prime Time, Forrester polled 297 IT decision-makers. The survey revealed that DNS attacks are commonplace, and this has made DNS security a top-line concern for companies and organizations.

Forrester found 51 percent of respondents reported experiencing DNS-related attacks, 38 percent of whom said they had experienced man-in-the-middle attacks, which DNSSEC is specifically intended to prevent.

Forrester researchers also found that while DNSSEC may not yet be widely understood – only 43 percent of respondents said they had heard about DNSSEC and knew what problems it solved – the majority of business IT leaders who do know about it plan to deploy the technology on their networks. Of those who reported knowing about DNSSEC, 90 percent said they would implement the technology within 18 months. Only five percent reported that they would not implement DNSSEC.

Facebook suffers second outage in as many days

2010-09-23T14:16:00.000-07:00

Facebook was struggling today as its popular social networking site went offline for at least 45 minutes Thursday afternoon. It's the second day in a row the popular site has had problems.

As of 3:50 p.m. ET today, the site was back up for some users, but still down for others. A "DNS Failure" message popped up when users tried to access the site.

AlertSite, a Web performance management company, reported that Facebook went down around 2:30 p.m. ET. And between 2:30 p.m. and 3:30 p.m., the site only had 38.46% availability. AlertSite also reported that Facebook was down at all 12 of its monitoring locations throughout the U.S.

With half a billion users worldwide, many of them admittedly "addicted" to Facebook, any downtime immediately stirs up a lot of buzz online.

As usual, a lot of users took to Twitter to voice their frustrations. "Facebook is down. In other news, office productivity is up across America," tweeted "MattMooreSC."

The outage occured one day after news leaked that Facebook CEO Mark Zuckerberg is donating $100 million to the struggling Newark, N.J. school system. That donation comes just ahead of the Oct. 1 release of The Social Network movie, which chronicles the creation of Facebook and reportedly doesn't always paint Zuckerberg in the best light.

"It seems Facebook is down and Zuckerberg won't bring it back up unless we promise not to see the movie," was how one Twitter user, "Someecards," put it in a tweet.

It's unclear whether the problem today was related to Facebook's problems on Wednesday, when a third-party networking provider took the site down for some users.
