No. I don’t mind at all. It’s a great marketing opportunity and they would be stupid not to take advantage of it.

Totally. Just like it's weird that more cigarette companies don't advertise outside schools.

Nobody ever died for using Cloudflare

That's kind of incredibly disrespectful to even compare the two

This is a great write-up, but one thing I don't understand is why the effect of withdrawing the BGP prefixes was instantaneous (if I understand that correctly), but it's taking hours (so far) to re-announce the prefixes. Why would it take so long to flip the switch back the other way?

You have to be careful turning something as large as Facebook back on. If you turn on announcements one place first, the entire internet will try to reach you through a single transit and overwhelm it.

All very amusing. But most amusing was that facebook employees' badges wouldn't work. Hilarious. Can't get in the office if facebook.com is not reachable. (or whatever the unreachable service was)

It wouldn't be the first time it's happened, and you would expect their network and security folk to understand single points of failure.

you would learn not to trust a first message you read on hackernews about what's going on inside

Is anyone else kinda put off by how Cloudflare keeps interjecting themselves into this situation? First with the Twitter posts and now this blogpost. They're a passive observer, not involved in this event, and yet they keep putting themselves in the middle of it. Cloudflare staff are not Facebook staff, they do not know how things actually went down to trigger the events that transpired. They are essentially doing gl…

It's merely an informative blog post on a topic many people are interested in. I see nothing wrong with Cloudflare just explaining what happened, even though they had nothing to do with it.

It is little stuff like this that makes it come off a bit self-aggrandizing:

> We keep track of all the BGP updates and announcements we see in our global network. At our scale, the data we collect gives us a view of how the Internet is connected and where the traffic is meant to flow from and to everywhere on the planet.

> Fortunately, 1.1.1.1 was built to be Free, Private, Fast (as the independent DNS monitor DNSPerf can attest), and scalable, and we were able to keep servicing our users with minimal impact.

It isn’t a big deal, and the posts are still interesting. It just makes me roll my eyes a bit.

Far fetched, obviously, but.... Jurassic Park, Dennis Nedry-type situation? Shut down the master systems to hide the theft (or in this case, destruction) of vital info. No key-card access means even non-need-to-know internal employees wouldn't see the deed, and plausible deniability is spawned for everyone else.

Considering they just had a whistle blower leak incriminating documents... I'd say this is plausible.

Edit: Also a great way to suppress the news of the whistleblower. Take the site down so the outage outranks news searches keyword "Facebook"

I kinda see your perspective; but I also mostly view them similarly to e.g. BackBlaze blogs - sure it can be viewed as taking smack about Samsung and Seagate drives failing, but I seem them as "things fail; what can we learn from it / here's our observations". And yes a little bit of self-advertising, but again, most tech blogs are, one way or another.

It just comes off as crass. Next time Cloudflare's CDN eats itself and starts vomiting up private customer data, Facebook can do a blogpost titled 'Understanding how Cloudflare exposed the private information of untold numbers of its customers'.

Sure they can. What’s CloudFlare going to do? Try to stop them?

Though I would expect something like this from Fastly more than Facebook.

Ah, so no playing oculus either?

Oculus customers were only able to play offline games during this time. Which I find concerning. I don't mind that FB employee badges didn't work because what would they do at their desks anyway and all exit doors have bypasses anyway so they can, and were, open, just rank and file employees couldn't access some spaces. Some of those spaces are secure and "fail closed" by design. Yes, its inconvenient but unlocking a…

What's it like paying to rent a gaming headset from Facebook?

My friends said they couldn't play Oculus
