I am curious - how did prior depeering "events" wind up being eventually resolved? What were the resolution times, if anyone remembers?

In the end, both providers lose, as customers buy real Internet transit from someone else.

OTOH, the industry as a whole probably gains. I have a client who's massively overprovisioned, multihomed with multiple Ts each to 3 or 4 providers now after being bitten a couple years ago when singlehomed to C&W and they depeered PSI. Funny that those PSI customers are getting screwed again now.
