Hi Wikitech Ambassadors,
I am a new hire of the Wikimedia Analytics team, it's nice to reach out to
you all for the first time!
I have to start with an apology since I missed to inform you about a rather
intrusive maintenance work to the servers the user sessions. I needed to
install the Debian Jessie OS on those servers, replacing Ubuntu Precise, as
part of one big infrastructure goal that we have. If you have experienced
issues with your session for brief amount of time during the past three
days (like 30 minutes at the time) it was probably due to me removing
servers from the available pool to work on them. I followed the least
impactful procedure but sadly I couldn't have avoided session loss.
Everything is tracked in
https://phabricator.wikimedia.org/T123711 for the
curious. I am planning to finish the bulk of the work tomorrow during EU
time, please feel free to reach out to me (elukey on IRC/Freenode) for any
question or to report any issue.
Thanks!
Luca
