Indeed, there does seem to be a problem with expired DS RR signatures.
A random sample of 1000 .fr child domains (out of 398,564 total known
to me signed .fr domains) returns DS lookup ServFail for 205 of them.

The associated RRSIG expiration times are:

        204 20200504145605
          1 20200504174835

We can estimate the standard-deviation at ~sqrt(n*p*q) or ~13, so
the 3-sigma interval is roughly 16% to 24% of the DS RRSIGs are
now expired, affecting ~80k signed domains.

I sent a Twitter message to "Vincent Levigneron", but likely some AFNIC
folks are on this list.

Yes.  See above.
