It should go without saying that we're mortified by this. While the immediate cause was operator error, there are broader systemic issues that allowed a fat finger to take down a datacenter. As soon as we reasonably can, we will be providing a full postmortem of this: how this was architecturally possible, what exactly happened, how the system recovered, and what improvements we are/will be making to both the software and to operational procedures to assure that this doesn't happen in the future (and that the recovery is smoother for failure modes of similar scope).
