Dear Wikimedia Cloud VPS/Toolforge users, If you use dumps/pageviews/other datasets available via /public/dumps on Toolforge/VPS instance, this email is for you! The underlying NFS storage server is being replaced. Your access path will remain the same, but the data may be stale or inaccessible during the migration to the new servers. Dates: The migration is scheduled for *April 2nd, 2018 starting at 14:30 UTC*, and is expected to last a few hours. Thanks! We'll send more updates closer to the migration date. If you have any questions, just let us know. Best, -- Madhumitha Viswanathan & Ariel Glenn

28 Mar '18

About 24 hours from now we're going to reboot a couple of servers[1] in the cloud infrastructure to apply security updates. Few WMCS users (and, in particular, no tools users) should notice any interruption. Nonetheless, a few services will be down: - New instance creation will fail - CI tests will stop running - Horizon and Wikitech may display incorrect or missing information Apologies in advance for any inconvenience! -Andrew [1] labservices1001 and labcontrol1001

Wikitech move this Friday, 2018-03-09 at 16:00 UTC
by Andrew Bogott 10 Mar '18

10 Mar '18

On Friday morning my time (10:00 CST, 8:00 PST, 16:00 UTC) I'll be switching the dns record for wikitech.wikimedia.org to point to a new server. This change should be largely invisible to users, but there are a few things to be ready for: - Most importantly, YOU WILL BE LOGGED OUT of Wikitech. So if you've been relying on a persistent session to avoid having to keep track of your 2FA tokens, today is the day to reset 2FA and record the new information. - The new Wikitech build uses a lot of updated software (Debian Stretch, HHVM, etc.). Although we've done some spot-checks, there may be new issues that appear for your particular use case. We'll evaluate these as they crop up, and decide whether or not to revert to the old server. -Andrew
