S3 must be the largest worldwide storage system, with regular updates to bring new functionality such as the new tables announced this week, but you never see announcements that it'll be unavailable for an hour due to an upgrade, and how often do you see outages, or significant issues. 2/2

I recently ran a workshop on Amazon's #FaultInjectionService. Just before, AWS introduced a new feature for testing Lambda with FIS, which I couldn't cover.

Luc, loving this - couldn't see a feedback option on the site, so hope you don't mind me sharing via bluesky.

Would be great if the filtering could also differentiate between news & blog so could only see news or blogs.

Thanks - just found out animated GIFs don't work here, or at least not for me.
