But the point is, you still have to syncronize the event of switching
routers and switching the DNS data, if you don't have the opportunity
to overlap.

And if an ISP goes bankrupt without notice (yes, it happens) and you
suddenly have to switch to another, how do you restore your DNS IPs
when you can't get any verification because your GTLD A records still
point to the old ones?
