No one needs to update their mirrors daily, but either way, rather than using horrendously inaccurate metrics I would suggest using rankmirrors or even reflector's "--fastest" option. From looking at the package, it seems to be its own source as well, which is actually against the rules. > I'm thinking about removing the mirror score from archweb's output and > more importantly, not sorting mirrors based on this score but rather > randomizing the list returned in [2].

Sounds like it fits the intended use-case anyway. -- Eli Schwartz
