See my earlier post .. the 17 year record for Irish Railways was not technically a cluster but a dual VAX with DT07 (DT03?) unibus switches that allow peripherals to dynamically switch from one server to another. 

As you correctly stated, it was the App that was up for 17 years.

All in all - a very nice testimonial to a solid technology solution.
