FTSE 100 Web Servers

19 January 2008

I wanted to do some independent research about the web server technologies employed by some of the top UK companies.

I used curl to send an HTTP HEAD request to each of the sites for companies in the FTSE 100, and looked at the server header returned. Results were as follows:

40% Microsoft
32% Apache
18% Unspecified
5% IBM

My guess is that several of the unspecified servers are really Apache, but it’s hard to say.

Here is the gory detail (pipe separated fields).
