know what Tool Labs is, you can safely stop reading this email here.
* There are some major projects in progress that could cause some
amount of disruption to Tool Labs tool/services.

Longer and more:
As part of the preparation for Wiki Loves Monuments 2017, we reached
out to Wikimedia Cloud Services team , 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
** 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 .
* All developers and those interested to get updates are encouraged to
subscribed to labs-announce and/or labls-l .
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. :)
Lily, on behalf of Wiki Loves Monuments international team
