Do you have a disaster recovery plan that starts with "A meteor has destroyed our primary data center."?
I do; that's my default scenario. If you can survive that, you can survive all sorts of smaller issues like network congestion, data center power problems, grid power problems, and zombie plagues (or flu, which is more likely.)
Depends on what you mean by 'survive'. I'd call a backup in google nearline sufficient for the meteor scenario, but that's going to be very slow and unpleasant to depend on for milder problems.
It's not sufficient. How quickly could you procure new hardware, install that in a datacenter, make it fully functional, and restore your backups? The answer is likely weeks/months. Could your business survive being offline that long? It sounds unlikely.
In an emergency you don't need new hardware. You can get cloud servers in minutes. If people have been practicing restores then it should not take particularly long to get the containers working again. A couple days to get things working-ish. That should be survivable while everyone focuses on the news coverage of the meteor.
But that's a true emergency situation. Don't go offline for multiple days for something that's reasonably likely to happen.
