OK sure, microsoft servers are ahead of unix based machines on the internet? Right, the world would not trust an ms server if you paid it all of bill gate's money. They are just not reliable enough. Word.

Did you know there are unix machines in the world that have not needed a reboot in over 20 years. Yeah that is the truth. MS boxes are slow as a dog and tied up with so much nonsense, that unless the real world has lost it's mind, this data is seriously flawed

You know the part about "Neither this or NetCraft’s data include internal servers, such as those running SharePoint inside the corporate network of many companies, so the actual percentage is probably even higher." is total BS. Sharepoint is a terrible app, and i am sure that those who are running it are suffering and now considering switching to a Linux based collab app. Sharepoint is a nightmare on top of another nightmare. Who would want that?

My company was literally paid by Microsoft to switch to Windows to host our >10k parked domains recently.

"Neither this or NetCraft’s data include internal servers, such as those running SharePoint inside the corporate network of many companies, so the actual percentage is probably even higher."

Nor does it include the 1000's of Apache/nginx in server farms behind a reverse proxy.

Hmmm.
Followed the url, and while MS has made a major, major gain here (and hats off to them, that's a lot of new sites under their banner) the "active sites" graph shows a slight loss; Not sure why this is (Netcraft themselves attribute it to the fact that almost all the gains are down to Nobis tech switching to iis, and given Novbis' largest provision is teamspeak servers - which are pretty much the same site stamped once per team - maybe that is why we are seeing no real gain in the active field). Still, nice to see Apache's reign threatened at last :)

Ben, I've never put much stock in this, as any mom and pop company with $50 and a grandchild who can write brochureware, will host on apache. It's not interesting. I don't care about how many snow-plow businesses are trying to get away with the cheapest hoster.

I am also interested in php on apache versus asp.net on IIS. I'd like to see comparisons of ROI between those solutions.

I am more interested in something like http://www.port80software.com/surveys/top1000webservers/, which answers the question.... if cost didn't come into play... what is used?

Well that was shortlived
