From the article: ``There are many factors which affect Website 
availability and performance from end user perspective, namely ISP 
Internet connection, server location, server parameters, programming 
language, application architecture and implementation. One of the critical 
parameters is a selected Operational System (OS). Most users often need to 
select between Linux and Windows, two popular choices for web servers. By 
providing free monitoring service, we at mon.itor.us collected large 
amount of data to perform a unique analytical research examining OS 
correlation with uptime and performance.
...

Summarizing, statistically Linux based servers provide better availability 
and response speed than Windows servers. Absolute leader is NetBSD in both 
categories; OpenBSD and Solaris also demonstrate good results.

We hope this data will be valuable for our community in their hosting 
selection process.''
