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 Podtech.net web site was unavailable early Sunday and offline again this morning. A dynamically updating chart showing podtech.net'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 WordPress.com rather than Microsoft).

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.
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 (cogentco.com) shows a brief outage this morning:
A dynamically updating chart of Cogent's web site performance is available. Netcraft offers a web site performance monitoring service that provides similar charts, along with e-mail alerts when an outage occurs.
WorldCom.com has been taken offline, erasing the web's last traces of the brand that became a symbol of white collar crime and the largest bankruptcy in U.S. history. The domains worldcom.com and worldcom.net have been taken out of the DNS database, meaning requests for those URLs return no response. The domains continue to be owned by MCI, Inc. the WorldCom successor that was bought earlier this year by Verizon for $7.6 billion.
When a company is acquired, its domain names are typically redirected to the web site of the acquiring company to capture potential customers searching for the old URL. Redirection services are freely provided by most registrars. But worldcom.com and worldcom.net have no A record listed in their DNS settings, suggesting the domains have been intentionally taken offline to "retire" the name.
The spam-fighting service Blue Security has been under siege by spammers and digital attackers in recent days. On Tuesday it wound up sharing its pain with a large chunk of the blogosphere. When Blue Security's web site was hit by a distributed denial of service attack attack (DDoS), the company temporarily repointed www.bluesecurity.com to a blog on Six Apart's TypePad service. The DDoS traffic appears to have followed www.bluesecurity.com to its new home, overwhelming Six Apart's network and knocking its TypePad and LiveJournal services offline for nearly eight hours.
LiveJournal hosts more than 1.8 million active blogs, according to its stats page, while TypePad is home to thousands more, including many prominent blogs. In a status advisory, Six Apart said a "sophisticated" DDoS struck at 4 p.m. Pacific time and continued to affect its services until past 11:30 p.m. "This has affected all of Six Apart's sites, causing intermittent and limited availability for TypePad, LiveJournal, TypeKey, sixapart.com, movabletype.org and movabletype.com."
The DNS change for www.bluesecurity.com to an IP address on Six Apart's network (18.104.22.168) was first noted on the North American Network Operators Group mailing list Tuesday night. Internal links on bluesecurity.blogs.com indicate that the blog was configured to operate under the www.bluesecurity.com URL. Further confirmation came from other blogs, including The SunBelt Blog, which linked to a post published early Wednesday on bluesecurity.blogs.com and cited it as appearing on www.bluesecurity.com.

Rackspace is the most reliable hosting company site this month, followed by Datapipe and iNetU. Rackspace was perfect this month - it experienced no downtime, and not a single failed DNS request was seen from any of our monitoring points during April. This marked the first flawless month for a host since Datatpipe did it in January 2005, while German host Komplex had a faultless month in March 2004.
This month's top three hosts have consistently been among the strongest performers in our Most Reliable Hoster surve. Rackspace was the most reliable host six times in 2005, compared to four times for Datapipe. INetU made the top 10 six times last year, and was the most reliable host for the second half of 2003.
Three Linux sites are found in the top 10 this month, three on FreeBSD, two on Windows and two on Solaris.
