I just discover that there is an error message on our website https://translation-council-support-group.web.cern.ch/
"# Site under maintenance
translation-council-support-group.web.cern.ch is currently under maintenance. We should be back shortly. Thank you for your patience."
I don’t understand what is the problem.
I did the updates for Drupal 9 with one of your colleagues and he said it would be ok.
Now, I don’t know what to do, could you please help me?
