Network maintenance Thursday, 2018-10-04 at 16:00 UTC
by Andrew Bogott 04 Oct '18

04 Oct '18

Routine network upgrades are scheduled for Thursday which may result in brief WMCS service interruptions. In particular, Wikitech and Horizon may stop working, and instance creation/deletion/updating may briefly fail. The network engineers have reserved a two-hour window beginning at 16:00 UTC (9 AM Pacific time). Their worst case scenario is 30 minutes of downtime but if all goes well the interruption should not be noticeable, just the time to unplug a cable from one switch and plug it into another.

Ubuntu deprecation plans
by Arturo Borrero Gonzalez 28 Sep '18

28 Sep '18

Hi! We would like to share some information regarding Wikimedia Cloud Services plans for deprecating Ubuntu, specially Trusty. Ubuntu Trusty's end-of-life is April 2019 and the WMF decided to consolidate in a single operating system, which is Debian. In Cloud VPS, projects containing Ubuntu virtual machine instances have been contacted by means of a Phabricator task. Toolforge users aren't affected by this right now, because Toolforge itself is currently running Trusty. But we are already working on the next, Debian-based, Toolforge version. All this information, more details (and timelines), can be found on this Wikitech page: https://wikitech.wikimedia.org/wiki/News/Trusty_deprecation Please, let us know any question or doubt you may have. Best regards.

NFS maintenance this Thursday 2018-09-27
by Brooke Storm 25 Sep '18

25 Sep '18

At 6pm UTC, Thursday 2018-09-27, we’ll be taking the primary tools/project NFS system offline for a brief moment to attempt some upgrades, which should cause load to climb a bit and then settle. This should be a relatively low-impact change and has been thoroughly tested in a separate environment, but if anything goes wrong with the process, corrective action may cause a few minutes of problems.

Very brief NFS maintenance today 2018-09-17
by Brooke Storm 17 Sep '18

17 Sep '18

At 6pm UTC, we will be briefly resetting the main NFS server for tools and projects to upgrade the tooling around NFS there. This should cause a brief climb in processes waiting for IO and then that will settle out. If things don’t operate as expected, rolling back the change could take a few minutes, but that seems unlikely. Please let us know if there are prolonged issues in the #wikipedia-cloud channel.

There are currently 57 unclaimed projects on https://wikitech.wikimedia.org/wiki/Cloud_VPS_2018_Purge. I will start shutting down unclaimed projects at the beginning of next month, and those projects will be left behind in the future network migration[1] and, eventually, deleted. If you see anything in this list that you care about, please indicate that the project is in use on the Wikitech page. Here are the 57 projects that are currently unmarked: aicaptcha bots bstorm-test chicotestproject ci-staging collection-alt-renderer contributors deep-learning-services discourse-wam download etytree fastcci glampipe globaleducation hat-imagescalers hound iiifls1 ircd jupyter maps maps-team matrix mcr-dev mediahandler-tests mediawiki-docker multimedia mw-api-testing mw-extension-ids newsletter nonfreewiki openocr orig pagemigration piwik project-smtp rdfiodev reading-lists redirects reportcard sentry services services-testbed t136871 test-twemproxy tor traffic wcdo wdq-mm wikibrain wikidata-page-banner wikidata-primary-sources-tool wikidumpparse wikifactmine wikimetrics wikisource-tools wikistream wlmjudging [1] https://phabricator.wikimedia.org/phame/post/view/112/neutron_is_finally_co…

Datacenter switchover on September 11
by James Hare 10 Sep '18

10 Sep '18

All, As you may have read about in other venues, the Wikimedia Foundation will be conducting a switchover of datacenters on September 11 and 12, with the switch back to occur on October 10 and 11. During the switchover and switch-back events, the wikis will be in read-only mode. Cloud VPS and Toolforge are not affected by these switchovers. However, if you run bots or scripts that make edits to the wikis, they may be unable to make edits during this time. This should appear to your bots as the standard read-only mode which occurs unplanned on the production wikis from time to time. Please let me know if you have any questions. ---- James Hare Associate Product Manager Wikimedia Foundation https://wikimediafoundation.org
