I worked on a team deploying a service to European Sovereign Cloud (ESC). Disclaimer - I am a low level SDE and all opinions are my own.

AWS has set up proper boundaries between ESC and global AWS. Since I'm based out of the US I can't see anything going on in ECS even in the service we develop. To fix an issue there we have to play telephone with an engineer in ESC where they give us a summary of the issue or debug it on their own. All data is really 100% staying within ESC.

My guess is that ESC will be less reliable than other regions, at least for about a year. The isolation really slows down debugging issues. Problems that would be fixed in a day or two can take a month. The engineers in ESC don't have the same level of knowledge about systems as the teams owning them. The teething issues will eventually resolve, but new features will be delayed within the region.

While it’s good to remain anonymous to avoid reprisals , once that’s done no one should care about upsetting their employer in an open forum. Despite what a corporation says they don’t own you, your thoughts or your voice.

Still it sounds like it would be the optimal choice for a redundancy zone in some senses since its probably not going to have any accidental dependency on us-east-1.

Sure, but what really prevents
