Very similar issues here in the New Orleans (Metairie) area - TV works uninterrupted, but our upload speeds drop to zero intermittently. I am certain that Cox is aware that there are large outstanding issues, but the current "fix" seems to be to send a tech out. My supposition is that they have jammed too many people onto the same node after the hurricane to restore some semblance of service. Our service can work fine for a while with normal speeds, but the declines are almost always around times when you would expect heavy usage (after work, evening, first thing in the morning).
