> Is there some reason why "global" services aren't replicated across regions?
On AWS's side, I think us-east-1 is legacy infrastructure because it was the first region, and things have to be made replicable.
For others on AWS who aren't AWS themselves: because AWS outbound data transfer is exorbitantly expensive. I'm building on AWS, and AWS's outbound data transfer costs are a primary design consideration for potential distribution/replication of services.
