I’m not really sure we’ve changed much that should affect this.

Which graphs specifically?

You’ll often need to shift-refresh after an svn up to clear cached javascript, 
but that shouldn’t affect the graph auth, because that’s just checking you’re 
allowed to view those devices/entities, which is immediately short-circuited if 
you’re a global-view or admin user anyways.
