> 100x missing the plan either means extremely poor planning or they screwed up something very very badly.
Like most airliner accidents, this is probably an unfortunate combination of both of those things happening at the same time. My guess would be they have fairly decent planning overall but there's one (or more) small-ish areas where their planning is extremely poor - which crossed over with a screwup in a very specific fashion that laser focussed on that particular piece of poor planning. The "this can never happen" immovable object and the "You can't do that" irresistible force.
Aviation has paid with so much blood resulting in tight regulations and internal controls to get the point where any current accidents are unlikely edge case scenarios. [1]
SaaS has lot more tolerance for failure, so my money is it is something simpler but difficult to get implemented in large org.

In a ideal world this incident should impact their revenue, growth and stock price substantially.
It is unlikely to do so, because of stickiness of enterprise customers, no better alternatives, compared to say Google, Facebook, Amazon where a minute of downtime is immediate quantifiable revenue loss so FAANG really obsess so much over how many 9s of uptime.
The typical management of enteripse app companies like Atlassian have no incentive to do anything beyond cursory lip service and get away with under investing in tech.

[1]3 years back i would have stood by that, but after Boeing 737 max twin disaster and systematic problems leading to it , i am not so sure those lessons are not forgotten.
