All national census data from February 2016 (when this sort of data started to be published, as part of the Fast Issues update) up until the server crash in April 2024 is still invisible, almost six months after we went back online. Examples of this can be seen on my WA Endorsements trend page and Kyupaa's Population trend page, both of which have April 25th as their first data point. (However, regional population history graphs have all data available.)
There was some concern about this a few months after the crash, but site staff did not say anything except to clarify that the data would be visible again one day. Do we have an ETA on this or are Elu, Aav and friends still working on it?
