Hi all,

If you are not a Tool Labs tool/service developer and/or you don't know what Tool Labs is, you can safely stop reading this email here. :)

TL;DR * There are some major projects in progress that could cause some amount of disruption to Tool Labs tool/services. * To stay on top of the schedule for such disruptions and/or to provide feedback when you can, please make sure you're subscribed to lab-l and/or labs-announce.

Longer and more:

As part of the preparation for Wiki Loves Monuments 2017, we reached out to Wikimedia Cloud Services team [1], cc-ed, to give a heads up that Wiki Loves Monuments is happening ;), we'd like to know more about scheduled maintenance on Tool Labs between September 1 and December 7 (which is high activity time for this community), and hear if we (the developers of WLM tools and services) can get special support during this period from the team. Here is what we learned and we'd like to share with you:

* The team doesn't currently have concrete plans for major maintenance in this period, however, * they do have several major projects in progress that could cause some amount of disruption as they reach the deployment stage. These include: ** migration to a new cluster of wiki replica databases, ** migration of NFS dumps to a new cluster of backend servers, ** and a complete replacement of the networking infrastructure used for the OpenStack virtual machines. * All planned maintenance around these projects will be announced on the labs-announce mailing list [2]. * All developers and those interested to get updates are encouraged to subscribed to labs-announce and/or labls-l [3].

Regarding support from the team if something goes wrong:

We are asked to get support through: Phabricator tasks, the labs-l mailing list, and asking questions on the #wikimedia-cloud irc channel.

One note that we also mentioned on this list last year: If you do have critical services that cannot tolerate downtime, please do let me know. I'd like to have an inventory of such services and keep an eye on them, please. :)

Best, Lily, on behalf of Wiki Loves Monuments international team
