Has PKIoverheid been comprimised?
"PKIoverheid has been compromised or otherwise is untrustworthy through its link to Diginotar"
Its not PKIoverheid that is untrustworthy, its any certificate that comes from Diginotar.
I'm guessing that this is probably "game over" for Diginotar. Are there any other companies that belong to the same owners/parent company? If so we should consider blocking them too.
