10 minutes is too short given how the restarts are mostly unannounced these days. On Release which is pretty much all reachable by highway many times 10 minutes isn't enough to make it home. Not too shabby when horses are hitched, but leading something tame or simply on horseback means if one can't be back online when server returns (since there's no way of knowing if it's 10 minutes or 10 hours) one's horses risk theft, logging in to untame summons, logging back in a troll convention and getting smacked around while game finishes loading... Bad enough that all these resets are aging the hell out of people's herds.
