I guess I should start writing down things I've learned over the past few years running a local #RuralBroadband ISP business. Some of them concern particular technologies used right now and will be obsolete in a few years or weeks. But some things never change.
In the past few hot days we've had one router and two ODU power supply failures. The lesson: never put home-grade electronics in the attics of poorly insulated houses without air-conditioning. Fortunately the rains came and it's colder now. How I waited for those wonderful thunderstorms. Oh, wait.
Just got a call from a customer: their router fried after a nearby lightning strike. Fortunately their ODU, some 12 metres above the ground, survived – we won't have to climb up to replace it.
Diagnosing this was easy. Convincing them to find a computer with an Ethernet port and bypassing the router was hard work.

Still waiting for a call from service person for mine.
The first day, their recorded message said the had lots of outages.
Today they were all fixed, and yes I had restarted everything.
So now waiting anxiously by the phone* for a call.
