Software that uses /data/scratch may see some disruption tomorrow when I merge https://gerrit.wikimedia.org/r/c/operations/puppet/+/695447/ <https://gerrit.wikimedia.org/r/c/operations/puppet/+/695447/> around 20:00 UTC
In order to make the NFS it works on more resilient and healthy, the cluster it runs on is migrating to DRBD failover like Tools home and project uses. The current setup is quite broken.
If you are running something against scratch when the patch becomes active in your project, you may see some issues like a stale NFS handle. If that doesn’t resolve quickly, please let us know in Libera.chat: #wikimedia-cloud

* The #wikimedia-cloud IRC channel is moving from Freenode to Libera.Chat.

There has been a lot of activity over the last 2-3 days related to
staffing changes on the Freenode IRC network . The Wikimedia IRC
Group Contacts (GCs)  evaluated the situation and decided that
moving the Wikimedia IRC channels from Freenode to the brand new
Libera.Chat IRC network  would be the best course of action .
So, we are moving!
A new #wikimedia-cloud channel has been created on irc.libera.chat for
this Wikimedia sub-community to use. The old channel on Freenode still
exists and will be maintained at least until we can get all the bots
moved, our documentation updated on wikitech, and we see more folks on
the Libera channel than the Freenode one. Messages to our channel in
either IRC network, as well as the Telegram channel , will be seen
on all other channels.
There is a new subpage on meta  for information on how to create a
new account for yourself on Libera.Chat and other related information.
There is also a tracking task  that you can look at to see various
activities that the community hopes to take action on to complete the
One last thing: The #wmhack Freenode channel is bridged to
#wikimedia-hackathon on Libera.Chat. The new channel name will make it
easier for the GCs to help manage spam and other issues that come up
occasionally on IRC. Don't miss the fun of our 2021 virtual hackathon
from Friday, May 21st to Sunday, May 23rd!

We will be doing an upgrade to the CloudVPS edge network Thursday 2021-05-06 @
15:00 UTC that will likely impact user experience, including Toolforge.
We scheduled an 1h operation window. During that time, intermittent network
interruption, packet loss and other network problems are to be expected.
The edge network maintenance will affect how virtual machines (and Toolforge
tools) contact NFS, wiki-replicas, wikis API endpoints, and, in general, any
network traffic that flows leaving or entering the cloud (also known as
More information on the operation can be found in phabricator  and in
