Scoble News Bogs Down

It's not often that a hiring announcement knocks a web site offline. But the blogosphere is abuzz with the news that Microsoft blogger Robert Scoble is leaving to take a position at a video blogging start-up. The news has triggered a burst of traffic to Scoble's new employer, PodTech, whose web site is struggling to handle all that link love. The web site was unavailable early Sunday and offline again this morning. A dynamically updating chart showing's web site performance this morning is available.

"PodTech’s site crashed this morning under *massive* traffic surge under the Scoble-effect," the company said Sunday when its site returned to service (but before today's outage). "Slashdot wasn’t a factor, since it didn’t carry a link to PodTech. The site crash was all from massive blog traffic." To date few blogstorms have invited comparison to the Slashdot effect in their ability to overwhelm sites with traffic. Slashdot reported on Scoble's departure, but linked to the announcement on the Scobleizer blog (which will continue, as it is hosted at rather than Microsoft).

Six Hosting Companies Most Reliable Hoster in May

Ranking by Failed Requests and Connection time,
May 1st - 31st 2006


Six hosting companies share the top spot this month, with INetU, Hostway, IPower, New York Internet, Pair Networks and Tiscali all sharing the top spot as the most reliable hosting company site this month.

The six-way tie is a first for the reliability survey, as three and even four providers have shared the top position in the past. The showing reflects a strong month for hosting reliability, as the winners each had just 0.01 percent of their DNS responses fail, just a hair short of a perfect showing. All six companies have finished atop the survey at least once previously.

It was a particularly good month for providers hosting their home page on FreeBSD, four of whom (INetU, iPowerWeb, NY Internet and Pair Networks) shared the top spot with two hosts on Linux (Hostway and Tiscali). Overall, five Linux sites are found in the top 10 this month, four on FreeBSD and one on Windows.

June 2006 Web Server Survey

The Internet experienced its strongest site growth ever last month, powered by a surge in blogs and free web sites. In the June 2006 survey we received responses from 85,541,228 sites, a gain of 3.96 million sites from the May report. This is the largest one-month increase in sites in the history of the Netcraft survey, surpassing a gain of 3.3 million in March 2003, although the 2003 gain was larger in percentage terms (8.5%, compared to 4.7% this month).

Microsoft continues to gain share in the web server market, chipping away at Apache's commanding lead. The number of hostnames on Windows servers grew by 4.5 million, giving Microsoft 29.7% market share, a gain of 4.25% for the month. Apache had a decline of 429K hostnames, and loses 3.5% to 61.25%.

Apache's lead over Microsoft, which stood at 48.2% in March, has been narrowed to 31.5%, a shift of 16.7% in just three months.

The largest movement of sites from Apache to IIS was once again at Go Daddy, with over 1.6M hostnames moving from Apache to IIS this month. While those parked domains were a major factor in Microsoft's gains, Windows also saw solid growth in active sites, hostnames that contain content and likely to represent developed web sites.

Blogging services enjoyed strong growth, paced by Google's Blogger, which added more than 660K hostnames. The global nature of the blogging phenomenon was seen in large increases in blogs hosted at Germany's Intergenia AG and Japan's, both of which run on Windows web servers. Windows servers also got a boost from Microsoft's Office Live service, as it began to open its beta offering to more users.

Apache's loss of hostnames is due to decreases for Linux at a number of hosting companies. In addition to Go Daddy, six hosts reduced their use of Linux by 40K or more, including leading UK provider PIPEX Communications, Lycos and Zipa.

Most sites ready for SSL progress

Despite the enormous success of SSL for securing web traffic, there has been little technical change in the way that SSL is used for secure HTTP in the ten years since SSL version 3 was introduced. Although it has been around since 1996, most browsers have continued to make connections compatible with the older SSL version 2 protocol. But now the major browser developers are aiming to drop SSL v2 completely; export-grade encryption ciphers are also to be dropped.

SSL version 2 was supported by Netscape 1.0, back in 1994, and it was made obsolete by SSL version 3, published in 1996. But while SSL version 3 was soon widely supported — and over 97% of HTTPS sites also support its successor, TLS — most browsers have continued to make SSL-v2-compatible connections, in order to stay compatible.

The Mozilla project first suggested disabling support for SSL v2 a year ago, and now also plan to drop weak ciphers. Internet Explorer 7 will disable support for SSL v2, and IE on Windows Vista will not support weak ciphers. And Opera version 9 will disable SSL v2 and weak ciphers.

Up until a year ago, when developers began talking about dropping SSL v2, there were still significant numbers of sites that only supported SSL v2. But server operators have got the message now. Out of the top 20,000 SSL sites (as ranked by users of the Netcraft Toolbar), only 20 sites (0.1%) require SSL version 2. This is reflected across the wider survey, with around 0.1% of sites requiring SSL v2.

Cogent Network Outages Affect Some Sites

Network services provider Cogent experienced network outages this morning, which reportedly caused broader availability problems for web sites and networks that rely on Cogent for connectivity. Traffic on major backbones appears to have returned to normal.

Cogent's network spans 29,500 miles of fiber and connects with 1,750 networks in major U.S. markets. Our monitoring of Cogent's business web site ( shows a brief outage this morning:

Melbourne IT Buys WebCentral in Australian Merger

Domain reseller specialist Melbourne IT said today that it will acquire WebCentral Group for $61 million (about $45.7 million in U.S. dollars), combining two of Australia's most prominent Internet service providers. The deal is the latest in a flurry of acquisitions in the past month as consolidation accelerates in the web hosting and domain industries.

Melbourne IT manages domain names purchased by customers of Yahoo Small Business and Microsoft's new Office Live hosting service, along with many other hosting providers. WebCentral is Australia's largest hosting company as measured by active sites, with 25.8K sites. The deal continues a trend in which domain registrars and web hosts have expanded into one another's specialties.
