Are we talking reliability or repeatability
..... The fifth nine is _incredibly_ hard, and _incredibly expensive._ ........

Starting from "we can improve anything to the degree that we can measure it" I think once we have figured out how to get reliability we have also learned how to measure it and therefor we can repeat and scale reliability. Good example, a 1960 Ford compared to a post Asian invasion Ford of today.
Apple is not new to reliability in either hardware or software. This ME generation Cloud deal is looking more like a management issue with each passing day. Garbage in, Garbage out. According to Apple 1% of their customers are not getting service and haven't been for several days.
The rumors are rampant about causes of Apple's ME generation roll out problem 1) initial large outage caused by cut optical cable. 2) current 1% outage caused by single server.
Lets say there is no truth in any rumor. What is known then. 1) a single problem can take down much of Apple's promised and paid for service. 2) If there was a disaster plan it does not seem to be working. 3) If there is a back up system it too does not seem to be working. 4) If there were redundancies built into the system they don't seem to be working.
What is questionable is if there was a well tested primary system in place for this new product rollout? Considering the crabbing Apple has been doing with their apology letters concerning their rollout marketing, there is considerable evidence that a tested system maybe a generous, although doubtful description of the system in place at the time of rollout.
None of my comments go to fixing Apple's ME generation product rollout, that's Apple's problem. People and companies tend to do what they have done before. We get to decide who we want to be a conduit for our treasured thoughts and information in the future. Our frustration today is largely based lack of service and lack of open communication between our trusted service provider and us the customer who have already paid for that service.
Most of us have had email service for years from other providers, maybe tens of other providers. We need to ask ourselves if Apple's service and conduct is typical? I am retired for the computer industry, worked the last 20 years as a test engineer. What is going on at Apple with this ME generation product release does not speak well for the field of testing, but you already know that.
