Today I will be migrating the mailing lists from a
very old server (lily) in Amsterdam, to a new server (sodium) in our new Ashburn data
center. Mailman will be upgraded to version 2.1.13 along the way.
During the migration, mail will be delayed as all data will need to be transferred to the
new host. No mail should go lost, but no new mails will be sent out during the process
until done, and the web interface will be unavailable. This shouldn't take about one
hour, if all goes well.
I will report here when things should be back up and running. Afterwards, please let us
know of any new issues, in bugzilla or on IRC (#wikimedia-tech). We don't expect any
problems, but as with any software upgrade or migration, this can't be guaranteed...
The mailing lists server migration is now complete - Mailman is now running on server
sodium.
As some people pointed out, my message earlier today was indeed sent out with the wrong
Date header. I simply redirected my old mail and edited it a bit, forgetting that the Date
header would not be adjusted by my mail client. Sorry for that. :)
The Mailman migration went smoothly, and I'm not aware of any problems. Please let us
know in Bugzilla or on IRC (#wikimedia-tech) if you're experiencing any new issues.
Unfortunately we needed to change the IP address of
lists.wikimedia.org for this
migration. Some large e-mail providers (e.g. Google) are rate limiting reception of mail
messages from the new IP (208.80.154.4) because it's not known and whitelisted yet. To
prevent further mail delivery delays today, I've configured the new lists server to
forward mails that would otherwise be delayed via the old mail server and old source IP
address again, for the time being.
Thanks,
