The politics is exactly the point of my comment.

The professional way to write a blog post like this is from your own perspective. Identify the proximate cause (the peer), name names if you must, talk about how awesome your own systems are, show some of your monitoring if you like, and talk about what you'll do in the future to be even more resilient to this class of problems.

That's all to the good and much of Cloudflare's blog was exactly that. Would've been fine if they left it like that.

Acknowledging there is no postmortem (yet) but then pointlessly speculating about what it might contain is what I have a problem with.

I don't speak for Google but if I found out we had written a post like this, I would speak up and advocate to change it.
