Broken links to metadata

Dear Debian masters,

I just had a look at https://packages.debian.org/wheezy/thunderbird and 
found several broken links:

http://metadata.ftp-master.debian.org/changelogs/main/i/icedove/icedove_52.2.1-1~deb7u1_changelog
http://metadata.ftp-master.debian.org/changelogs/main/i/icedove/icedove_52.2.1-1~deb7u1_copyright
http://sources.debian.net/patches/summary/icedove/1:52.2.1-1~deb7u1/

They all report HTTP 404.

Thank you for your attention and my favorite operating system. You rock!
