That's awesome, but why publicize it? This isn't an act of contrition for you, no one outside your team really needs to see your dirty laundry, and actually comes off as unprofessional to me. The gitlab team is a team, and you take responsibility as a team. Placing names and initials in the liveblog makes it look like SOMEONE is trying to assign and pass off blame, even if that is not what is happening.
Presumably in the coming days there will be a number of team meetings where you discover what went wrong, and what the action items are for everyone moving forward. The public looking info just needs to say what went wrong, how it is being fixed, and what will be done in the future to prevent it from happening again. I don't need names to get that.
