DNS outages

My company uses for DNS hosting and we were hit by its troubles
this weekend.  I know there are companies that offer backup DNS services,
but those seem to be aimed at companies that host their own DNS, which we're
not really interested in doing at this time.  Are there mainstream DNS
hosting companies that allow customers to use a second company for their
backup DNS?  Does allow this?

You can outsource your DNS, but you better retain a server locally on your
network, so that you suffer less from that particular shared toothbrush.
