Odly enough I am not allowed to post contracts with IBM to an internet post, something about confidentiality...

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.

And you (who made the initial assertion that linux cant get the same number of 9's) have provided nothing at all other than opinion.

You can find one reference here.
