Not really based on a user’s IP.
Based on BGP peer routing, so it’s actually physical location of users/ISP/trunks etc, and how they connect to the rest of the world networks.
The geographically local data center can announce a shorter route for a specific IP (block) than a data center on the other side of the planet, so the packets get routed to it

Most multinational web apps will have different deployments for different countries.
Locating the servers geographically closer to the users reduces latencies and costs.
Running different deployments allow them to tailor more closely to local regulations, without having it impact everyone else

Standard bottles of wine are generally 750ml tho. So a pint would be less.
The current small bottles are 187ml (personal?) and 375ml (half/demi).
So, 568ml just doesn’t fit. And I have no idea who would actually produce them.
