Getting latest Arabic po files

I tried to visit https://translations.documentfoundation.org but it gives me this error message:

A username and password are being
requested by
https://translations.documentfoundation.org.
The site says: “The server is closed
for maintenance. Please check back
later”

From where can I get latest Arabic po files?

Translations (including Arabic) for the master branch can be found here. Instructions for downloading are on the Developers page.
