Not easy, sure, though EC2 has plenty of support for different availability zones (as does RDS) so it's not impossible (though you pay normal bandwidth charges between availability zones, as opposed to getting it for free).
So I guess it boils down to figuring out how much outages cost you. In the case of these businesses, probably not enough to warrant investing the time and skills to have plans and infrastructures for small-scale disasters like this, given that they're relatively uncommon.
