Hello, the datacenter is located in Florida (famous for being hit by hurricanes) 6 meters above sea level & above near river 25 kilometers air line from the sea 0,7 kilometers from the river which goes into sea in like 30 kilometers Is there a reason to worry?
Google is building some of the data centers under the sea too. May be you will see the cloud based datacenters as well in future. This data center in Florida does not have any threat as all contingency measures must have already been taken.
If the datacenter goes down, due to a hurricane / flood 25 km from the sea... you (or at least Florida) have bigger issues than a dead datacenter...
Over the years we have moved all our infrastructure from Florida and California to avoid potential natural disasters.
You don't have reason to worry, during the construction of the data centers, meteorological features of a particular region are taken into account.
