I used to serve the block_log at an uncapped 1 Gbps, but since people tended to ignore my suggestions, they were downloading it over and over again, despite already having their own copies locally. Usually would not be a problem, except "usually" it's heavily used when there IS a problem. ;-)

Even if you would have faster download, still whole replay have to wait until you download the whole. When doing re-sync you download as you go.

Is the year of GTA6 and IPv6 the same year? ;-)
