The right way to handle this is to get your own IP allocation and do BGP
out both providers. Then the internet can reach you over both internet
connections and when one goes down all traffic is routed through your
other connection.

Another feasible, but poor option: proxy your services out in the cloud
and have it be intelligent enough to be able to reach your content over
both providers and properly failover when one goes down.
