Cisco had a bug a few years back that affected metro switches such that they would not withdraw routes upstream. We had an internal outage and one of my carriers kept advertising our prefixes even though we withdrew the routes. We tried downing the neighbor and even shutting down the physical interface to no avail. The carrier kept blackholing us until they shut down on their metro switch.
