Reminder:  There will be some brief service interruptions, starting in about an hour.  We don't expect VMs or Toolforge tools to be affected by this. -Andrew -------- Forwarded Message -------- Subject: Network maintenance Thursday, 2018-10-04 at 16:00 UTC Date: Fri, 28 Sep 2018 13:19:36 -0500 From: Andrew Bogott <andrewbogott(a)gmail.com> Reply-To: andrewbogott(a)gmail.com To: Cloud-announce(a)lists.wikimedia.org 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.
