What happen to mailing list archives?

It seems someone has tried to migrate the mailing list archives
from mailman to some new fangle code.  This has broken the archives
for at least freebsd-numerics@, freebsd-office@, freebsd-net@

As a comparison, simply go to

https://lists.freebsd.org/mailman/listinfo

and follow the links to freebsd-numerics and freebsd-toolchain.

Can this be fixed?
