fastly RCA is underwhelming - no info on what was the component, what happened and how the situation was tackled.

I think a public company will never dare go into as much detail as bunny did. Or maybe it is just the size of the organisation that discourages that.

Cloudflare's RFO blog posts are incredibly detailed. Each time I read one, I feel reasonably confident that they have learnt from the mistakes that lead to that outage and that it shouldn't happen again.

Yeah, but Cloudflare is accountable to the US Congress, they better be transparent.
