I was also planning on adding some mirroring by adding 2+ A records to some names:
The mirroring setup is finished. There's a master server now handling dovecot.org and a mirror server handling www/hg/wiki. Would be nice to get another reliable fast mirror server if someone wants to donate one :) Requirements are:
- Apache2 with WSGI
- Mercurial
- Patched moinmoin
- ssh + rsync so I can push changes immediately
I have a script that builds all of those on a freshly installed CentOS 5.6 (and a kickstart config to do the install too).
- hg.dovecot.org can be mirrored either with hg itself pushing changes or calling rsync
hg commit hook calls rsync immediately
- www.dovecot.org can be mirrored with periodic rsync. The most frequent changes are mailing list archives and nightly tarballs.
www itself doesn't change unless I change it manually. When a new mail arrives via mailman, it gets rsynced to mirrors within 5 minutes. This is done by rsyncing the current month's all files/dirs.
- wiki*.dovecot.org could also be rsynced and set read-only. A patched MoinMoin could show "Edit" links as pointing to master.wiki*.dovecot.org where editing is allowed.
Edits are rsynced to mirrors within 5 minutes.
Also there's a nightly script that rsyncs everything just in case (except in case of mailing list archives only current+last month, since they're so huge).
BTW. Apparently there's still something wrong with dovecot.org's reverse DNS record. It appears to be ok, but some DNS servers have cached it wrong. I don't know why. We've complained to the ISP. Also dovecot.org is currently sharing IP with some other stuff, but should get its own IP some day.
