> What strikes me the most is that this whole "event" would have hardly even registered on anyone's radar (it affected less than 10% of their traffic during early hours of the morning.

It wasn't just CloudFlare who were affected. And the time of day is completely irrelevant, I live in Australia and was affected by this during evening peak time. Some very popular services (eg: discord) were completely knocked offline.

I think you're underestimating the impact of this event.
