Request Let's Encrypt remove our domains from their blacklist

Once we've established certificate transparency monitoring (Bug 1270657), contact Let's Encrypt to request that our domains be removed from their blacklists.

The method to request Let's Encrypt remove our domains from the blacklist is to create a bug for Legal (Product: Legal, Component: Trademark) requesting a Mozilla attorney to produce a letter, on letterhead, asking for these changes, and send it to the ISRG/Let's Encrypt security@ email address. ISRG will then verify the attorney really sent it, and the change will take effect. This process comes from ( ) and :ellee clarified how to contact legal in ( )
I've established certificate transparency monitoring which emits events into MozDef when new certificates are issued. We're still talking in Bug 1270657 about what to do with that data but the requirement for unblacklisting Lets Encrypt is satisfied.

Jeff Bryner has gotten the go ahead from security council so we're clear to be unblacklisted.

I'll open the bug with Legal and link it here.

letsencrypt has suggested we establish DNS CAA records (instead of having them manage the details of what we want blocked). They'll setup the blocks on their side but we should transition that responsibility to ourselves.

I've asked in this ticket if Akamai (DNS provider for some of our domains) now supports CAA records :
:jcj Now that the letter has been sent to ISRG ( ) do you know if/how they will notify us that we've been unblacklisted?

You and Jeff are going to get an email when it's official. I have reason to believe today's the day, however.

OK, it's officially done. There'll be an email sometime... but it's done.
Excellent, I've tested it and confirmed it's working.
