There is no specific concern. Any KSK operation can be performed without the physical 
TCRs presence. There is no other source of confidence except TCRs, and their absence 
or accessing the private key without their presence isn’t good for trust.

I understand the extraordinariness of the moment, and if you have no choice, you’ll jump to 
Option 2 and Option 3 then. Is the disaster recovery procedure (Option 3) the one that should’ve 
been done on Verisign’s disaster recovery site? Does it require to access the cards? Or we’re 
discussing the non-disaster remote ceremony?
