There is another down downside of leaving the CATV off for the night is, once the amps go cold it might not be that easy to restart them in the morning! They are on 24/7/365, then all of a sudden they are goning to be without power for the night, they will cool down, maybe a tiny bit of moisture will get in....and bang.
Another well thought out plan by the monkeys, I mean managment (calling them managment is a bit 1984 new speak-ish, as they couldn't manage a **** in a brothel!)
The other downside is my porn downloads won't be finished overnight
