Google Cloud Platform has various regions for hosting their services, e.g. West Europe 2 for London based services.
However, with Firebase, there seems to be no way to configure where content is hosted. Even if integrated with a GCP project (via Blaze plan) there doesn't seem to be a way to configure a region for storage or functions other than the default US Central region.
1) Is there possibly a way to configure which region Firebase is hosted in?
2) Does the current US-centric hosting affect performance from locations such as the UK? For example, if someone navigates to my web app in London, is the web page calling GCP cloud functions based in the US, which in turn is fetching data located in, for example, London?
