RIP and a big thank you from me.
Great while they lasted. At least the laid the path that led to Letsencrypt. Except I sometimes miss the hassle of navigating their authentication system.
I wonder if it was mere coincidence that Google et al laid off them until free Letsencrypt was up and running. Otherwise many of us with SSL sites would have been held hostage by the rapacious CAs if it had been killed off earlier.
