Package translations missing in ftp.debian.org?

Hello,

some time ago my Debian testing computer stopped showing Italian
translations for packages in apt.

When I run apt update I see that it downloads English translations, eg:
http://ftp.it.debian.org/debian testing/main Translation-en.diff/Index [27,9 kB]

English is the only language available from
http://ftp.debian.org/debian/dists/testing/main/i18n/

while the same directory for stable contains all languages
http://ftp.debian.org/debian/dists/stable/main/i18n/

Is something broken in my configuration or package translations should
available also for testing?
