At https://en.wikipedia.org/wiki/Barack_Obama?action=info the Page protection section says:
- Edit | Allow only autoconfirmed users
- Move | Allow only administrators
but it doesn't indicate the length of the protection (indefinite, in this case).
Similarly, https://en.wikipedia.org/w/index.php?title=List_of_burn_centers_in_the_United_States&action=info
doesn't indicate when the protections are set to expire (27 June 2015, in this case).
