Jobs available at Netcraft

The Netcraft Web Server Survey is a survey of Web Server software usage on Internet connected computers. We collect and collate as many hostnames providing an http service as we can find, and systematically poll each one with an HTTP request for the server name.
In the May 2002 survey we received responses from 37,574,105 sites.

Totals for Active Servers Across All Domains June 2000 - May 2002

iPlanet is the sum of sites running iPlanet-Enterprise, Netscape-Enterprise, Netscape-FastTrack, Netscape-Commerce, Netscape-Communications, Netsite-Commerce & Netsite-Communications.

Microsoft is the sum of sites running Microsoft-Internet-Information-Server, Microsoft-IIS, Microsoft-IIS-W, Microsoft-PWS-95, & Microsoft-PWS.

Platform groupings are here.

Around the Net

Zeus overtakes Netscape-Enterprise

Zeus has overtaken Netscape-Enterprise on a straight count of hostnames in the Web Server Survey, reflecting the relative effort the two companies have put into making their servers suitable for shared hosting systems. The Netscape-Enterprise figure had been propped up for quite a long time by a single system run by Verisign, and most of this system has been migrated to Microsoft-IIS over the last year. However, Netscape-Enterprise has around four times as many IP addresses in use running web sites as Zeus, and generates significantly more revenue, reflecting its much better penetration of Enterprises, particularly in the US.

Overtaking Netscape provides Zeus with a highlight in a very mixed six month period, which has seen a successful fund raising round combined with some significant staff departures, including Adam Twiss, who co-authored the server, co-founded the company, and successfully ran it from his bedroom while a student at Cambridge,

By coincidence, Randy Terbush, co-founder of the Apache project, who started Covalent as a single person company in the mid-90s, has recently left Covalent, also not long after a successful funding round in which the company raised some $18M of new investment.

Interland buy Dialtone Internet

This month, two of the largest dedicated server companies have combined as Interland bought Dialtone Internet.

Superficially, this seems to make a good fit, geographically and technically. Interland is the largest hoster of Windows 2000 sites on the Internet, while Dialtone has majored in Linux. The combined company has over 141,000 IP addresses hosting web sites, placing it third behind Verio and Alabanza, each of which operate large HTTP/1.0 shared hosting systems.

Interland and Dialtone Operating Systems by IP Addresses, May 2002
Operating System	interland.net	dialtoneinternet.net
Windows	72,001	2,153
Linux	34,580	25,833
FreeBSD	8,772	221
Solaris	15	0
unknown	496	99
Grand Total	115,864	28,306

United Linux an oxymoron

Today sees the launch of unitedlinux.com The choice of name perhaps makes plain how diverse the Linux industry can be, since Red Hat, Debian, Cobalt and Mandrake, - as far as web sites go, four of the top five Linux vendors and distributions - are not part of the initiative.

Dogfood

Remarkably, this month Netscape-Enterprise has been replaced on netscape.com . Although Sun and AOL have dissolved their iPlanet joint venture, and netscape.com is wholly owned by AOL, the move still seems likely to create useful marketing collateral for Microsoft, and indeed, Covalent and Red Hat too, as they sell to enterprises where Sun/Netscape is the present incumbent. Looking more carefully, Netscape-Enterprise had already been replaced on some of Netscape's European sites. For example, netscape.co.uk now runs Apache, while in France netscape.fr runs Microsoft-IIS. It may prove challenging for Sun to convince people that they should not migrate away from Netscape-Enterprise when the Netscape sites themselves have done precisely this.

Reports and Interactive Queries

Reports are provided showing server usage for the Internet as a whole, and for selected domains, with links to all the sites responding to the survey. A facility for you to check what server a particular site is running now is also available. The same form can be used to ensure that a particular site is included in future surveys. A directory of sites running in developer domains is also provided, while the sites discovered by the survey can be explored.
