if a mirror manager don't do a good job, he'll just be taken out of the ring after a while. If we depend 100% on Amazon, and if there's a problem, the mirroring will be down for the time being and we won't be able to do nothing about it. > If we actually understood each time PyPI > broke and fixed it none of this would be a problem; I'm not blaming anyone > for that, but it's also not going to change and adding lots of mirror > systems just adds more systems with exactly the same management problems > that our current system has. Yes but the difference is that you don't put all your eggs in the same basket: it's very unlikely that ALL community mirrors will be down at the same time, thus a fall-back mechanism on the client side will raise the availability automatically. About Amazon: what will happen in 5 years with their offer ? will our Cloud-PyPI infrastructure will still work ? what will be the workload to maintain it ? You can't be 100% sure the Python community will be able to dedicate that time. PyPI works today because it is not forced by a third party to evolve, it can evolve as its own pace. On the contrary, once the mirrors system is set, it will be dead easy to add/remove a mirror in the ring, and each node won't act as a SPOF IMHO it's a bad idea to make this piece of our infrastructure depend on one third party commercial entity, where we can provide a community answer. Now, a mirror could use Amazon, that would make more sense to me.
