Sounds an extreme rollercoaster, that one. Take it easy on yourself

Alas I know all too well what that kind of day is like... although you really did have a stunner.
Without knowing more I wonder if it had genesis in a morning low while you were asleep between 4 and 6am. The 17 could be rebound effect, and the rest also rebounds, exacerbated by over-correcting each time. EG, bolusing and not eating at any breakfast. Delayed reaction from the 16 units (sounds a lot? what is your typical amount for lunch?) you took in the afternoon to correct, kicking in at night. These things sadly are possibilities. Extreme highs and lows usually have a rebound for which can then cause another. Corrections need to be careful not to overcompensate.
For me, when I am high insulin response can be severely retarded, taking up to twice as long to kick in and then doing it all at once. So if you stack insulin you run the risk of it all kicking in quickly once the body decides to absorb it.
First bit of advice for dealing-at-the-time is to take it easy with your corrections. Eg, eat half a meal instead of skipping it. Use a more moderate extra dose to correct if high. Because almost always things do catch up with you... later...
Going by your (probable) repeated morning hypo, I think this might point to the cause of the problem with your basal being too high during the night into the morning. Unless you are correcting/bolusing in the evening/night time, in which case that might be the problem.
Sorry I can't be more clear, it's late here. Ask more questions if what I say doesn't make sense to you...
