With Hackage down, now seemed like a good time to push this issue again. It's such an important site to us that it's really rather a shame there are no mirrors of it. I have a personal-and-business server in a data center in Newark, with a fair chunk of bandwidth, which I'd like to offer for a permanent mirror. Is there interest in this? Who do I need to talk to for it to happen?
At the recent hackathon we were working on hackage mirroring. By this we do not mean just using rsync to sync the current combination of filestore + cgi programs that make up the current hackage implementation. We want to make it easy to set up dumb or smart package archives and to do nearly-live mirroring. We have a pototype hackage-mirror client that can poll two servers and copy packages from one instance to the other. This assumes the target is a smart mirror (e.g. an instance of the new hackage-server impl). We also need to be able to target local "dumb" mirrors that are just passive collections of files.
Strategy-wise, I think the best approach is round-robin DNS, since that's transparent to the end user - everything would still appear at the URL it's at now, but behind-the-scenes magic would let things keep working when one or the other site is down. I haven't personally set up such a system before but I'm willing to take on the burden of figuring it out.
This is a somewhat orthogonal issue since I think you're talking about multiple master smart servers that can accept uploads. Duncan
