IMO, it requires more than this.  Ideally, one-time, token-based (i.e. SecurID)
passwords, coupled with SSH, is the best solution, especially with the turnover
rates at providers these days.  

Of course, this also requires that all the backend (RADIUS, configuration management,
etc..) and out-of-band systems are secure, which is another rathole altogether.

As for this incident, well, I think if the intial intent of the 
"divulging message" was simply to remind folks to change their 
passwords, the points been made.
