[BlueOnyx:23708] Let's Encrypt invalidates 3 million certs

Hi all,

Please check if you might be affected by this issue. If so, you might
have gotten an email from noreply at letsencrypt.org to the email address
you had specified during the LE cert request.

Basically it's like this: They had a bug in the verification process for
SSL certificates which affected certs with validity for multiple
different domains.

In our case the cert for www.blueonyx.it was facing revocation tomorrow
as it was affected due to being valid for 13 different domains including
blueonyx.info, blueonyx.co.uk and others.
