Water intrusion?

Is it raining a lot in Paris?

From the information I gathered, this is an incident in the GlobalSwitch datacenter in Paris.

The cooling system leaked, and this started a fire in an electrical room.

The big issue here is that one Datacenter failure brought the whole region down, this is very abnormal.

Yes, there seems to be a design flaw here. There should be no SPOF in region design.
