I've used the Kwalitee and CPAN shields/badges in some of my GitHub/CPAN repositories for years. Recently, though, it seems the badges stopped working—for example, see Syntax::Construct : kwalitee doesn't display at all (but I can view the image directly ), the CPAN badge shows the current version as ?.?.?.

My speculation is it's caused by some changes to CPAN and its infrastructure at the Perl Toolchain Summit this May.

Does anyone have any idea whom to ask?

See Re: VERSION section in POD for a previous mention of the shields in the Monastery.
