This is great for the planned changes, but real-time changes to
respond to Internet dynamics won't work well with such delays. If you
are multi-homed to provide a backup, you would like for it to respond
more quickly than 4-72 hours, I'll bet. So if you have PI space but not
your own AS, your backup route would look like a novel origination,
but you sure wouldn't want it delayed.
How common are such cases? Should the solutions cover them also?
Should there be special procedures to deal with special cases?
