Hey everyone, This mean wikilables will be down during that time.

Best ---------- Forwarded message --------- From: Yuvi Panda yuvipanda@gmail.com Date: Mon, Feb 6, 2017 at 9:28 AM Subject: [Labs-l] [Labs-announce] Tools DB / Labs Postgres DB maintenance on 15 Feb 2017 To: labs-announce@lists.wikimedia.org

Hello!

Tools DB and Labs Postgres DB will be undergoing maintenance on 15 Feb 2017 for about 6 hours starting at 1700 UTC and will be unreachable for some of the duration. Most users shouldn't experience issues if their code reconnects properly when the server stops accepting connections (we'll failover to slaves when doing maintenance). Some tables will not be available for a short period of time, but the tool owners of those tables have already been notified (see https://phabricator.wikimedia.org/T127164 ). We'll try to minimize downtime as much as possible.

We will be upgrading the operating system from Ubuntu Precise to Debian Jessie in preparation for EOL of Ubuntu Precise (in April 2017). We'll also take this opportunity to upgrade Tools DB to Mariadb 10.

All data should be preserved in this migration. Follow https://phabricator.wikimedia.org/T123731 for more information!

Thanks!
