5gbps fiber and then a 5G business internet backup failover via UniFi UDM-Pro, all on UPS with a standby Generac. We can take a power and ISP outage simultaneously and have a second or so connectivity hiccup.

Specifically for a lab it’s less of an issue. I run UPSs at my network equipment/NAS and at desks at home - with people working from home & also cameras recording to the NAS, a power hit would be problematic.

Mechdyne TGX is made for exactly this - it works beautifully. I ran across it while finding options for remote video editing during Covid, and we had spectacular success with it (major sports TV network). It’s significantly more bandwidth efficient than the competition, which was critical for us due to limited vpn bandwidth at the time.
