Rollback behavior

Removes the tc netem qdisc from the pod's network interface.

Implementation notes

Uses tc qdisc add dev eth0 root netem loss PERCENT% CORRELATION%. Even small loss percentages (1-5%) can significantly impact TCP throughput due to retransmission overhead. Use abort conditions to detect if loss is causing cascading failures.
