I'm surprised you'd think sending civilians into a war zone is a good thing.
It's not like Amazon doesn't have tactical teams on call - if that was a priority, I'm sure it would have been done. But like any good datacenter provider, they have offsite backups, and I'd expect the damaged hardware will just be written off.
1.5M civilians already live in Bahrain. This usage makes the term "war zone" meaningless.
War zones tend to have lots of people in already, and many of them really want a job.
