Requests returning 404 on default classic static namespace

It appears all the classic endpoints are returning 404 for the namespace static-classic-us, however the data is available for the namespace static-10.0.7_48520-us, probably missing some alias or something.

It is possible to find the current namespace by requesting one of the available search endpoints as a workaround.

EDIT: I used the latest retail namespace by mistake, the classic data is not present even for search endpoints.
