Actually, your provider does a service to you. When you fixed your
flapping for good, you can call your provider and have him reset
the damping holddown. If he would pass this flapping on, all/most/many
peers/upstreams of him would have your prefix dampened, and almost
nothing he can do about it. You stay down until all their reuse
timers expire.

Propagating the instability hurts more than damping it early at the
source.
