Hello everybody,

I am pretty sure that the first thought reading the email's subject was "whatttttttttt!!!!???? Are you crazy Luca?". There is a valid reason, please keep reading :D

In T243934 we worked a lot to reduce the complexity of our client nodes, and the result is that all stat100x have the same configuration (please see https://wikitech.wikimedia.org/wiki/Analytics/Systems/Clients), that includes Jupyterhub. SSH access to nodes was also simplified a lot, see https://wikitech.wikimedia.org/wiki/Analytics/Data_access#Access_Groups.

The notebook100x hosts have the downside of having little disk space for home directories, and it would be great to reduce the amount of hosts handled by Analytics. This is why I am announcing that at the beginning of June I'll start decommissioning the notebook100x nodes. I have added https://wikitech.wikimedia.org/wiki/Analytics/Systems/Clients#Rsync_between_... as reference to a quick and easy way to transfer data between notebook and stat boxes, but please feel free to reach out to us in https://phabricator.wikimedia.org/T249752 for any issue/doubt/etc..

Thanks in advance!

Luca (on behalf of the Analytics team)
