I like it, when people talk about definitions, especially for some common / widely use terms. The more common a term is, the more one is "afraid" to ask about it. And since we cannot glimpse into other people's minds, we can talk about completely different things using the same words.

Availability Models talks about the definitions of "high availability" - incredibly popular term in computer science! It doesn't examine all the availability models, despite its name. Rather, this article brings up a question: so, what the heck is "high availability" and how can we define that based on our actual needs?

P.S. Also, I didn't know about the PACELC theorem. It always feels so cool to learn something new!
