IIS sees more gains over Apache

Netcraft's February 2007 Web Server Survey results have been released this morning. The latest data confirms a definite trend that kicked off about year ago: web servers running Microsoft IIS are on the increase and Apache is on the decline in terms of 'market share':

"Microsoft-IIS gain 935K sites, continuing an advance that has seen Microsoft steadily chip away at what once seemed an insurmountable lead for Apache. In our Feb. 2006 survey, Apache held 68% market share, giving it lead of 47.5% over Windows (20.5% share). In this month's survey, Microsoft's share has improved to 31.0%, narrowing Apache's advantage to 27.7%."

I would say 'haven't we seen that before' after noticing the IIS uptick from '01 (maybe when it came out?), but that Apache downturn is eye-popping - especially as it appears to be at IIS's proof-in-the-pudding.

Nice find.

Didn't Microsoft make a deal with some number of Domain Registrars and had them switch their 'parked domain' service from Apache to IIS... Hence all the reported gains are a result of IIS serving useless, non-existent, spam type of mass domains?

Apache vs. IIS - nope... the data I quoted refers to 'active sites'. What are 'active sites'? From Netcraft's January 2007 survey release: http://news.netcraft.com/archives/2007/01/05/january_2007_web_server_survey.html

"Microsoft's gains were more pronounced in active sites (hostnames that contain content and likely to represent developed web sites)"

Nice try though.

It would be nice to know the exact definition for an "active site"...

Here is something...

http://survey.netcraft.com/index-200007.html#active

The methodology actually looks good. Dumps the majority of sites hosted on the same IP, and compares uniqueness via an md5 sum of the html tag structure of a page.

Though I'm sure if there is a way to manipulate those numbers, its being done.
