Seems that ampage.org donīt accept IPīs from Brazil. Iīm from Rio de Janeiro and about 2 months ago I try to open this site and browser returns 404. Yesterday I try again with a little proxy installed, wich changed my IP and the site become alive :).
Maybe others user have same problem, so can team site verify if Brazilian (or other locations) IPīs are blocked.
Thanks in advance and sorry for my bad english.
