Hi everyone, stat1004 has been reimaged (with /srv preserved), and is back in operation. It should work just as before, but with newer versions of kernel and system software.
Luca has prepared a document that explains how to reset virtual envs if needed: https://wikitech.wikimedia.org/wiki/Analytics/Systems/Jupyter#Resetting_user_virtualenvs If there is anything out of place, just let us know. The updates to stat1005 and stat1007 will happen next week at the earliest, preceded by separate announcements at least 24h before the individual reinstalls.
