If you are referring to the recent UAE datacenter attacks, AFAIK Amazon's services worked as advertised, but obviously a redundant resource is only as good as the number of copies you have left, and eventually 3 of 3 datacenters were hit.

Apparently not all AWS resources/services are redundant - some are advertised as single location, and then it's up to the customer whether they choose to pay to make backups elsewhere (e.g. in a different region) or not.
