Mine is about 800mbps. ISP is CCC, and gets about 100mb DL'ed per second along with the upload speed being about 400-450mbps depending on traffic/ping.
While don't have an actual library close to here, we got one at the uni and the entire uni internet is 495MBps actual up/down speed (meaning 495MB down in a second and up too). Not from a real ISP though, it's a government line intended for schools and unis.
I go to the library tons. Their internet speed can vary from being the fastest thing on earth to being super slow you cannot use it. Normal speed is 50mb/s
