The most obvious things would be to make feedback faster… Implement congestion controls further
up stream with reduced buffering throughout the network, selective technologies like WRED, etc.

As RS said, sure, but all come at a cost either in performance, equipment, support, or some
combination thereof.

I concur.

Is anything the ISP could avoid to alleviate this occurrence, or is it entirely a 'server-side' issue to resolve?

As I understand it, the problem being discussed is an oscillation that is created when the reaction occurs faster 
than the feedback resulting in a series of dynamically increasing overcompensations.
