My experience over the decades is an insider dirty secret: downtime doesn’t really affect revenue.
You can hear all about this if you turn up to Harry's at 7pm on Thursdays, or at many of the other tech events in Seattle. Lots of current and ex-Amazonians out there with stories!
Regardless, that wasn’t my point — the outages you mention do drive customer churn and cause sales problems. Ie AWS outages do impact revenue.
These are called Fight Club issues, and are restricted access issues that don't show up for most team members. Gotta cordon off the real hairy bugs!
I expect AWS outages affect revenue. But on the score of the number of companies… very few are in a similar position of AWS.
