With round-robin DNS neither provider has to do anything. It's all
handling by the name servers returning multiple IP addresses when a
host name is resolved. Which IP address is returned first rotates on
a round-robin basis.

We're a small company, so ISP redundancy has simply been a dream for us.
But I assumed, maybe erroneously, that there were other, larger companies
that had ISP redundancy as a matter of course. If they do, I guess they
would already have techy people to do whatever might have been required in
case of an outage.

Large companies have their own block(s) of IP addresses allocated
directly from the RIR. This allows them to multi-home their IP
addresses in a way that is completely different from having IP
addresses which belong to the provider.

If I recall correctly, for the U.S. and other areas that get their IP
addresses allocated by ARIN, you have to be requesting a block of a
minimum of 2048 IP addresses to get a direct allocation, and that's
only if it is multi-homed (multi-homing requires a direct allocation).
If it's single-homed then the minimum number of IP addresses is larger
(because you should be getting your block of IP addresses as a
sub-allocation from your single connectivity provider).
