Glad you agree on API nodes because that is actually what my post was about. :-)

Hive has enough witnesses (although more is always better) but does not have enough API nodes because people think they are very expensive to run.

The specs required to run a witness node are so low these days that you can run a backup witness on a 9 year old laptop (admittedly with 8Gb RAM and 500Gb NVME SSD and i7 4 core - my old Macbook Pro was a beast in its day).

A laptop is the poor man's uninteruptible power supply and 4/5G or alternate wifi (neighbours) can provide internet redundancy.
