The site is under maintenance.
Most probably the CPANTS databases are being regenerated from scratch behind the scenes due to the major change in Kwalitee metrics or the update of relevant modules/perl. Usually this maintenance takes about a day or two, and some of the information may be old or missing tentatively. Sorry for the inconvenience.
