It's currently been about 3 weeks since the last data migration to data.stackexchange.
The help page says that data is updated weekly. Why hasn't that been happening?
Surely this should be an automated process, run by crontab?!
Oops, yeah this was busted on 2 levels. The part where the job crashed and burned annnnnnd the part that emails me telling me that, double fail.
It's working now, should be about 2 hour for SO to finish a refresh. After that finishes, it will run weekly on Sundays.
