This seems like a very naive response. We run on hardware that's lifetime is quantified not whether it will fail, but when it will fail. You don't know when that is, or how it will fail. The node could completely go away, or degrade enough that it begins to impact performance.

We also run persistent systems across the WAN. And, unfortunately, some of these things require the state to be maintained.

You can't just design these systems to be "better". There are often things outside of your control.

Based on your response, you seem to be the type of person causing pain for those with a pager.

Also, I'm sure the company that can make the Internet work every time, all the time, will make a killing.
