Hello,
Unfortunately, we had some disk space issues in our NFS server that required the NFS process to be restarted. This created all sorts of issues in Toolforge and Cloud VPS which we are still recovering from.
If your tool is not working and wasn't restarted automatically, please try to restart it manually (`webservice restart`).
We're truly sorry for the inconvenience. If you need help with a particular tool, please contact us on #wikimedia-cloud
Regards,
