Note that any failure in the GPS/GNSS radio hardware that actually
provides both the PPS pulses and the NMEA messages would be a failure of
both "ntpd sources".
Thus such a failure of NMEA+PPS would be more common than a failure of
NMEA or PPS alone.

.. and one failure experienced here was the presence nearby (RF-wise) of
a GPS jammer. All GPS receivers lost lock, PPS and NMEA. Interesting
to note which continued to provide an /unlocked/ PPS signal!
The PCs continued to sync with the Internet alone.
