SSL errors occur for TLS certificates issued on December 1

GMO GlobalSign's Status Page - SSL errors occur for TLS certificates issued on December 1.

@tdp_org this is a very cryptic statement. Are there any more details?

They logged in ct-logs which are not yet marked as trusted?

@pft I don't personally have any more detail but I believe so, yes. That's the only thing I can think of which makes sense.
AFAIK there's no vulnerability or incident other than incorrect config.
