iPowerWeb is the most reliable hostinig company site in June, followed closely by Hostway, as budget hosts continue to demonstrate that their networks can compete with those of high-end managed hosting providers.
iPowerWeb's shared hosting accounts start at $7.95 a month for packages that include a free domain and 10 gigs of disk space. Hostway, which ties for second with Above.net this month, offers "SuperPower" shared hosting accounts that include 150 gigs of disk space and 1,500 gigs of data transfer (no, those aren't typos) starting at $9.95 a month.
Leading managed hosting providers continue to turn in strong performance, with Datapipe, Navisite, Rackspace and New York Internet all among the top 10, which included four sites on FreeBSD, three on Linux and two using Windows Server 2003. Of the 50 major hosts we monitor, 34 had no measurable outages in June.
Network problems at Internet backbone provider Level 3 have caused some intermittent connectivity problems today for customers of several U.S. access providers. The issue appears to be related to network integration of Wiltel Communications, which was acquired by Level 3 last fall. By late afternoon, East Coast time, Level 3 was reporting that the situation had been stabilized. Level 3 is one of the largest providers of wholesale dial-up service to ISPs in North America and is the primary provider of Internet connectivity for millions of broadband subscribers through its cable and DSL partners.
Many sites hosted at Fasthosts, one of the UK's largest hosting providers, were unavailable for about 9 hours Sunday. Fastshosts hosts approximately 560,000 hostnames. The outage knocked out Fasthosts' own site, along with customers including Net4Now, which attributed the problems to a fiber cut at Telewest/BlueYonder. The fiber cut also affected cable TV service to about 100,000 UK subscribers who lost their signal just prior to the start of Sunday's World Cup soccer game, in which England defeated Ecuador 1-0.
Net4Now wondered how a fiber cut at a single connectivity provider could affect so many sites, given Fasthosts' statement that "every server enjoys a fully redundant Tier 1 connection so our customers never experience slow-down or service interruptions." The outage can be seen in this chart of the uptime for Fasthosts' main web site:

Several popular UK-based betting online betting sites have been hit by brief outages this morning, interrupting wagering on the World Cup. Sites operated by BetDirect and UKBetting were offline for periods of between 45 minutes and two hours during the same general time period.
Industry observers say as much as £1 billion ($1.84 billion U.S.) could be wagered on this year's World Cup, five times the betting volume for the 2002 event. It's not clear whether heavy traffic was a factor in today's outages, but that type of betting volume makes downtime quite expensive for online bookmakers. Historically, betting sites have been targeted by DDoS extortionists during major sporting events.
Netcraft offers a web site performance monitoring service that provides detailed uptime charts, along with e-mail alerts when an outage occurs.
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.
