There is one useful data point that came from the DigiNotar mess-up: we
now know, thanks to Mozilla, Debian, and the SSL Observatory what the
lower bound is for a failed CA to be considered too big to fail.

You must have issued some (unknown) number in excess of 701 SSL certs to
not see your root pulled from certificate-consuming software when you
mess up.

valid_certs where Issuer like '%diginotar%' → 701

So far, we only knew what the upper bound is to be considered too big to
fail, which was the number of certs issued by Comodo and Symantec
