Netcraft tracks web server/OS marketshare.
Some caveats:
- It's fairly easy to "trick" Netcraft with headers.
- Netcraft can only scrape pages that are publicly available. This means it misses databases, business logic, and intranet sites.
- It also means that their stats may be skewed by load balancers.
- And they're web biased, so they're not tracking MX servers, ssh servers, etc.
