[c-nsp] Multihoming

[Keegan Holley]

It looks like this subject has been beat to death so I'll skip the usual
about obtaining a /24 form ARIN and a public ASN.  Global load-balancing is
an option as it allows you to fail over your DNS entries to the second
providers IP space.  This pretty much negates the need for BGP if all you
were using it for was failover.  There are also companies that offer global
load-balancing as a service so you don't have to worry about managing the
box itself.  It's DNS based so the load-balancer itself can be anywhere in
the world technically.  Redundancy is usually taken care of as well.
