What time will the Presidential Debate be online AFTER it's aired?

I’m not talking about live streaming. I’ve organized a bunch of people to watch it together at 9pm (west coast time), but no one’s able to tape it. I’ve seen it on CNN, etc the next morning, but I don’t know how quickly they get up.

How soon is the whole thing available online? Experiences from the first one or the VP debate? Places to check? Ways to record the live stream on a laptop?
