what do you mean by "passing a yank test"? i assume "yank test" refers to unplugging the network cable abruptly from the server under test, but what exactly are you looking for when you do that?
A yank test on process and infrastructure is more than a 'did it come up'. It's a "if we totally nuke the thing" - say, were we to rip the hard drives out of a server, fry it, and recreate it - does it come up identicall(is).
