>>54133574doesn't seem that surprising assuming the server is not that far and you have large files, with 10mbps internet, which isn't even that slow, it was pretty normal before everyone got glass fiber, downloading a 4gb file takes around 6:40 minutes, I would guess the pigeon flies around as fast as a human runs except it ignores buildings and traffic lights so it could maybe cover around 2km in 6:40
the main problem would be the infrastructure, setting up and keeping the pigeons is expensive plus it's only useful for downloading large files which you don't need often, for normal internet usage it would be useless
