@Bob Schecter - I am not saying that Godaddy will get it right but it would not be hard for them to replicate or even improve upon the basic configuration recipe that the "specialists" are using.

Beyond that, they might actually be in a position to build up the sort of knowledge required to cope with edge case problems because they already have scale and are a mature, established company, presumably not under the same sort of pressure to make sky-high returns for investors at all costs.

This stuff is not rocket science, even the edge cases can be dealt with efficiently if you know what you are doing. Sure, dealing with Godaddy over the years has led me to have a few WTF moments, but there is no reason why they could not run a tight unit that offers a better service than WPEngine at a lower cost, and still be massively profitable. In fact, I am surprised the big hosts didn't recognize this opportunity a long time ago.
