There were three main groups looking for the RSADSI key: DESCHALL,
SOLNet (European based), and a private attack at SGI. To my knowledge
none of them excluded keyspace the others had searched.
You might call it luck, but at the time the key was found, the combined
keyspace searched by the three groups was a bit over 50%, even counting
in the expected number of duplicate keys searched.
