Unfortunately you can't set DNS TTL arbitrarily high (or low) without some resolvers ignoring your suggestion and using arbitrary values.

Most historical outages lasted minutes or hours. One arguably lasted much longer, when someone lost control of their servers due to civil war.
I haven't followed this closely, but have there been any... shall we say plain outages longer than six hours? That's not an outrageous TTL. Or a day.
