It's called "congestive collapse" or "throughput collapse" https://en.m.wikipedia.org/wiki/Network_congestion https://en.m.wikipedia.org/wiki/Network_congestion It's caused when a surge in traffic causes a self-reinforcing blockage that doesn't solve itself even after reducing incoming traffic below the pre-surge level. Network traffic planning is always a conflict between efficiency and edge case tolerance.
