[Engineering] Data center switch-over moving ahead next week: please stay available :)

Tue Apr 19 17:40:46 UTC 2016

An important note:

if you try to run a script on terbium, it will fail to execute.

While MediaWiki is switched over, you should use wasat.codfw.wmnet instead.

Sorry for not notifying this earlier.

Cheers,

Giuseppe
