Whenever I see solutions like this I think back to an org I worked at where a high-visibility day-long database outage gained upper level management attention. The response, after the managers talked to our vendor (IBM), was to re-architect everything to use HACMP clusters for all of our production databases company-wide.
That was followed by a couple years of 100+ hour/year cumulative outages due to HACMP stability issues, and an environment that everyone was deathly afraid to touch.
The hardcore network engineer in me appreciates the detail in these kinds of solutions, but these days the practical side of me is satisfied with usability and maintainability of SPOF cable access with a manual failover to mobile hotspot on the rare occasions that drops offline.
