Anyone needing that kind of stability should just use FreeBSD. They know how to put together a rock-solid system, and they have sensible release policies to ensure that their releases are very usable many years after first released.
Even the best "enterprise-grade" Linux distributions pale in comparison to FreeBSD and everything that it offers. It's a complete system that just works.
Just not for enterprise-grade businesses.. who wants a "complete system" that's almost completely dead like anything BSD (Berkeley So Dead)? With Red Hat, they have seven years of support for each major release from a regular subscription contract, and even extended life support contracts for more time than that.

Oops, jumped to add this comment, and wish I could delete it, since it has nothing to do with a country's request for censorship.
