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.
@EricLawton Ouch. The BTSs we use are holding up, but emergency power supplies on some of them are not in perfect shape. On the other hand, only two towers had serious problems in the past few weeks, and operation was restored in under five hours. Not bad, considering the distances.
