Hi, We are planning maintenance work on the following hosts at 20:00 - 21:00 UTC on Wednesday October 21. During the maintenance window, each host will become momentarily inaccessible for about a minute as we perform an upgrade. hue.wikimedia.org turnilo.wikimedia.org superset.wikimedia.org piwik.wikimedia.org For context on the change, see https://phabricator.wikimedia.org/T240439. Our scheduled maintenance can be viewed at https://wikitech.wikimedia.org/wiki/Analytics/Systems/Maintenance_Schedule . This will only affect the web interfaces. Any processes that are running on these hosts will not be affected (the machines will not be restarted). We'll send a reminder before the maintenance happens and message out when it is complete. If something doesn't look right, message me at razzi on Freenode or reach us at the #wikimedia-analytics channel. Regards, Razzi & the Analytics team
