No, each region is made of many data centers. US-EAST-1 is spread across Northern Virginia.
> Using only one AWS region is a bad idea. Period. In fact, I'd argue (thanks, BGP hijacking!) that using only Amazon services is a bad idea. If that is too difficult to manage for you, then set the appropriate expectations with your business managers and users. Your product is too cheap to support that high of an uptime requirement.

Have fun living on your planet where everyone has the budget and time for multi-provider multi-region setups. It's one thing to chide people for not having proper backups or never considering HA, but expecting every site to launch their own satellite to maintain continuity in case the internet fails is pretty pointless.
