Yes, I'm a real link monkey today. That's because my blog isn't working properly, so I have to post here. Anyway, this was interesting:
The gist of the article is even though Linux may be more secure, businesses are always having to upgrade systems and the process of changing a Linux application stack is so complex, the resulting downtime can be pretty harmful.
Of couse, studies like this are never exact, and I'm sure people will say they could have picked a better distro, or done things differently, or better admins, or used a backup and migrated to new systems to reduce downtime, and blah blah blah. To that I say: Install any new software on Linux without an internet connection available. It's IMPOSSIBLE.
