This is a "Cybersecurity chief" causing an intern-level IT incident.
In many industries, this would be a rapid incident at the company-level and also an immediate fireable offense and in some governments this would be a complete massive scandal + press conference broadcasted across the country.
The CTO created the update? Otherwise it's not the same situation
No but they could have easily created the culture that massively increased the probability of such mishaps... we have all seen how not OK work environment negatively affects deliveries right, or read about boeing fiasco(s).
Not an insider just to be clear here so maybe just really bad luck. But no benefit of doubt for the third strike.
Then again the CTO of Crowdstrike that had their anti-malware code update cause huge problems, is the same guy that was CTO of McAfee when their AV code update, caused huge problems.
