Yeah so it's been mentioned in the comments already, but to everyone in Fastly right now: I feel for you. Something like this must be insanely stressful, and not just during the outage. There will be (should be) a massive post-mortem. People will be losing sleep over this for days, weeks, months. :( Edit: There seems to be a major empathy outage in this thread. Disgusted but not surprised, unfortunately.
Call me old fashioned but the latest trend of showing "empathy" for a serious incident, then proceeding to dance around the aftermath of it, whilst people give themselves a pat on back in a retro/post-mortem, isn't the way to do it. People need to be blamed, and responsibility for actions taken (without covering asses)
"An atmosphere of blame risks creating a culture in which incidents and issues are swept under the rug, leading to greater risk for the organization."
