You usually get city level location information. Depends on your definition for 'far enough' if that works for you.

me-south-1 is about 250 miles away from me-central-1, but that's not far enough in this instance. Given that, I think city level location information should be good enough.

250 miles is pretty good for weather or not specifically targeted destruction (wildfire / industrial explosions / arson), but it's clearly not enough if your data is in a building targeted in a regional war. Assuming datacenters remain targets in wartime, I think it's fair to assume if one datacenter in any particular country is attacked, all the rest of the datacenters in that country are likely to be attacked, too. In that case, offline storage (tapes and things) in inconspicuous locations might be the way.

Kinda they do? Atleast our company knows the exact location of ours

No - and usually the reason is so they cannot be targeted.
