At 6pm UTC, we will be briefly resetting the main NFS server for tools and projects to upgrade the tooling around NFS there. This should cause a brief climb in processes waiting for IO and then that will settle out. If things don’t operate as expected, rolling back the change could take a few minutes, but that seems unlikely. Please let us know if there are prolonged issues in the #wikipedia-cloud channel.
