Fine. We've merely established that you can't point to a single public reference where IBM promises 5x9's of availability under Linux.

Try this Google search: site:ibm.com linux "99.999" returns about 483 results.

As you alluded to earlier, the results are for IBM's mainframe-class machines. But the difference between 4x9 and 5x9 availability is less than one hour per year. 4x9 is still an acceptable rate for many mission-critical applications, considering the cost difference.

Yep. I know. I've already looked into this issue. IBM isn't selling Intel-/AMD-class servers with 5x9 availability.

But the difference between 4x9 and 5x9 availability is less than one hour per year. 4x9 is still an acceptable rate for many mission-critical applications, considering the cost difference.

Whether some people can get by with 4x9's versus 5x9's is irrelevant. Many businesses don't have that luxury. And for those who need 5x9 availability, Solaris on Sun hardware is more appropriate for mission critical applications than Linux.
