Netcraft Toolbar for Firefox 3 – Win an iPod

The Netcraft Toolbar is available for the Firefox 3 web browser. The Netcraft Toolbar offers protection against phishing by using Netcraft's phishing database to block known phishing sites and provides a convenient mechanism for reporting newly discovered phishing sites.

In addition to blocking known phishing sites, the Netcraft Toolbar also displays a Risk Rating for all new sites it encounters. The Risk Rating — a user-friendly visual summary of the information displayed by the toolbar — evaluates new sites against characteristics of the phishing sites reported to date. Sites which are deemed safe will show a low Risk Rating, while riskier sites will show higher ratings based on a number of factors. To make it easier to judge whether you wish to continue browsing a site, the toolbar also shows which country and netblock the site is hosted in, and when the site was first seen.


Knowing which country a site is hosted in can help you spot risky content and highlight DNS poisoning attempts – if your US online banking site suddenly appears to be hosted in Russia, that would give good cause to be suspicious.

Some countries attract a large number of phishing incidents, often due to lax security or the increased likelihood of phishing sites staying around for longer. One particularly notable example is Cameroon, where the number of phishing attacks has exceeded the total number of sites hosted in that country. Netcraft publishes statistics on the phishiest countries in the world. You can also see how popular a site is with Netcraft's site rank.

A detailed site report shows further information about each site, including the web server's uptime:


Win an iPod

Netcraft gives away iPods to the top five reporters of validated phishing sites. A leaderboard tracks the top reporters for each monthly competition.

When you visit a page that you believe to be a phishing site, reporting it to Netcraft will allow other toolbar users to benefit from your vigilance. After you report a URL, Netcraft will review the report and block the page if it is confirmed to be part of a phishing incident.

The prizes can be won by any individual who reports phishing URLs via the web form, or directly through the Netcraft Toolbar for Firefox or Internet Explorer.

July 2008 Web Server Survey

In the July 2008 survey we received responses from 175,480,931 sites. The web has grown by 3.14 million sites over the past month, with Apache web servers increasing by 2.2 million and Microsoft IIS by 1.4 million.

Particularly strong growth is seen in lighttpd, which nearly doubles its total this month, rising from 1.5 million to 2.9 million and increasing its market share to 1.68%. lighttpd has overtaken nginx and Oversee to become the 4th most popular web server in the world. Users of lighttpd include YouTube, Wikipedia and the IM service meebo.

Much of this month's Apache growth was seen at, which gained 1.9 million further sites running on Apache. More than 95% of the sites hosted by now use Apache. Earlier this month, launched an enterprise-class managed hosting service under the branding of Planet Northstar, alongside dedicated servers under their new Planet Alpha branding.

Facebook Outage Affects Multiple Countries

The social networking site Facebook suffered a period of short outages yesterday. A spokesman told the BBC that the outage was not thought to have affected every country, but Netcraft found the site to be unavailable from all of its performance collectors, located in London, Pennsylvania, San Jose, Phoenix, New York, Virginia and Italy.

Facebook outage downtime

Facebook's popularity has continued to grow and is now the 33rd most visited site by users of the Netcraft toolbar. Originally called "The Facebook", the company renamed itself after purchasing the domain in 2005 for $200,000. By October 2007, Microsoft announced that it had bought a 1.6% share in Facebook for $246 million.

June 2008 Web Server Survey

In the June 2008 survey we received responses from 172,338,726 sites.

The total number of sites has increased by 3.9 million this month, with the largest gain being seen at, where 632,000 new sites maintain its position as the 6th largest hosting company in the world.

A large switch to the Bahamas was seen at Secure Hosting Limited, where 1.2 million sites were gained from Nameview Inc. The offshore hosting company offers web hosting and dedicated servers from its data centres located in the Bahamas and Jamaica, and even provides dual-homed hosting for a 100% uptime guarantee.

Most of the new sites at Secure Hosting Limited were using the Lighttpd web server both before and after the switch, so Lighttpd's market share remains fairly static this month. Microsoft's IIS web server grows by 2 million sites, boosting market share by 0.36%, but Apache remains in the lead with a total of 49.1%.

LiteSpeed loses more than 600 thousand sites during this survey, while nginx gains more than a million sites; more than doubling in numbers. The WordPress blogging system recently converted all of its load balancers to nginx, using the upstream hash module to serve 8-9 thousand requests per second. Netcraft's site report shows the main WordPress site switching from LiteSpeed to nginx in April. nginx is a web server and mail proxy server written by Igor Sysoev.

Mozilla Outage on Firefox 3 Record Launch Day

An outage affected the website on the day the organisation launched its Guinness World Record attempt for downloads of the new Firefox 3 browser.

The site was unreachable from around the world, occasionally responding with the message, "Http/1.1 Service Unavailable".

Mozilla uptime

Melissa Shapiro posted a statement on the Mozilla blog to say that their servers were feeling the burn and should be back to normal shortly. An earlier post stated that the record attempt would begin today at 5pm UTC, but Shapiro announced after this time that the 24 hour period in which the downloads will be counted will begin once the site goes live.

Netcraft was able to access the Firefox 3 download page again shortly after 7pm UTC, but the Service Unavailable message was still seen occasionally. For some period before this, the page was still offering version 2 downloads, yet a Mozilla press release confirmed that Firefox 3 had indeed already been released.

A follow-up post on the Mozilla blog officially announced that the 24 hour period had begun, with Guinness counting all complete downloads of Firefox 3 before 18:16 UTC tomorrow.

The outages also affected the website. Realtime performance graphs of the Mozilla website are available here.
