I made a quick test using wget and got 7MB/s when downloading the
kernel from puzzle and 3MB/s from the parabola repo. The first value
was increasing whereas the second was slowing down from an initial

OK, if these are indeed the correct values, I'm not sure if it makes
sense to get such a powerful server for a new mirror or if it makes
sense to get a further mirror _server_ at all.
A pay-as-you go model such as Amazon S3 or MS Azure CDN might be
interesting here. Mostly because I always wanted to work with such a
system, but also because it should provide the fastest downloads while
still being very inexpensive for such little data.
What do you think?
