Somebody on HN once mentioned maintaining duplicate/redundant deployment scripts for two different cloud providers. If one goes down you 'just' redeploy onto the other cloud provider. So you would be down for only as long as it takes to run a deployment and update dns.
Minimal additional recurring costs:
* duplicate storage (e.g. GCS and S3)
* engineering cost of maintaining/testing multiple deployments (non-trivial)
This feels very much like a five 9's level optimization that I would not find easy to justify.
It might also be worth investigating how Netflix handles this issue.
