The official report is available here: https://www.globalsign.com/en/customer-revocation-error/ To be clear, an intermediate root (not sure what this is tbh) was never revoked - we revoked a cross certificate between roots R2 and R1 and an unused/EOL CA under R2. These correctly appeared and continues to appear on the CRL, in fact it was included on the October 7th Root R1 CRL well before the OCSP incident. > > > > http://www.theregister.co.uk/2016/10/15/globalsign_incident_report/ > > > > They rolled back the revocation, but i thought that the BRs explicitly > > forbid that a suspended/revoked certificate be un-suspended/un-revoked. > > > > https://www.globalsign.com/en/customer-revocation-error/ > > > > is this revival/un-revocation of an intermediary CA allowed by the BRs? > > > I have just read that page, and find it utterly confusing and badly > written.

None of the actual end entity SSL certificates were ever revoked or marked as revoked either via CRL or OCSP. The scope of the users impacted by this depends on many factors, which are outlined in the report. Not all users were blocked from accessing sites with SSL certificates under R1. > 3.

We intentionally revoked 2 CA certificates as listed in the incident report - One old CA that had no live certificates issued under it, and the one cross certificate referenced above. We did not take actions to revoke any CAs other than these two; however as pointed out, the OCSP responders incorrectly created and provided OCSP status messages for CAs under R1 indicating that the CA was revoked. These CAs never appeared in any CRLs. > 4.

GlobalSign contacted as many of our customers as possible with SSL certificates issued under Root R1. Note that EV certificates are issued under Root R2 and were not impacted by this issue. > > Enjoy > > Jakob > -- > Jakob Bohm, CIO, Partner, WiseMo A/S. https://www.wisemo.com > Transformervej 29, 2860 Søborg, Denmark.
