I'm interviewing for a Production Engineer role at Facebook on Monday, thanks for providing relevant "do you have any questions for us" content.

I advise you against it. You can frame it in a different way though. Maybe ask how do they mitigate issues as big as these and their post-mortem procedure.

Doesn’t their world class team make such a long outage to be quite unlikely? How hard would it be to devote ample resources to a cover story for the “incident report”? Is the timing relative to the plethora of indictments relevant at all? Reasonable that this may be related to shredding of data and/or code, or even a cooperation to turn over data to government in secret deal?

That site relies on user reports. I strongly suspect users are reporting "my Internet is having troubles" because their FB, Messenger, etc. isn't working right. For example, in the comments of the T-Mobile outage page, there's stuff like "Haven't been able to upload anything to social media all day" and "Cannot send pictures through whatsapp and fb messenger".

Yeah in Turkey people thought government is slowing down/blocking the whole internet

To be fair, the priors lean into that rather than Facebook and Whatsapp having troubles.

Even with your platform there will be calls and pain, maybe even lies during an outage. BC-Recordkeeping or not

unscheduled outages are always painful and people will always call, I agree. But instant compensation is doing a better job at damage control that a status page. Keeping customer satisfaction even in bad situation is key in a world of high availability expectations. And with a distributed, non partisan metric sourcing about the availability of an API, it's not possible for a Service Provider to lie anymore. Feel free…

I don’t understand something: what kind of company is so down to the wire with cash flow that an outage requires income within seconds/minutes instead of weeks? Anyone with a financial runway so short that it can be described as “instantaneous” doesn’t sound like a customer you would want to be in business with.

I'm pretty sure a bunch of Erlang programmers being shoehorned into a PHP codebase is the literal definition of Hell for all parties involved.

Facebook is not a “PHP codebase.” I’d guess that fewer than 0.01% of CPU cycles at Facebook are used by PHP.

Isn’t a significant amount of the codebase in Hack, a PHP derivative?

There's something ironic about a social media company being forced to rely on a competitor to facilitate communication between them and their users.

Why? When Facebook is down, you cannot use Facebook to communicate about the issue. That is also reason why FB still uses* irc instead of messenger for coordinating how to resolve such issues. * Or at least used 1 year ago, when I was working there.

Hmm, I wonder if we could leverage that to make irc more popular again. "FB uses X" is often all the justification small startups need for picking a tech.

I’ve seen many systems go down over the last few days worldwide. Aside from the possibility of a mega-DDoS attack (which Facebook denies), all of these organizations have fairly diverse tech stacks to my knowledge. Google’s issue (supposedly) had to do with their Blobstore API, we don’t know what happened with Facebook, and many other, smaller services have had issues as well, including three intranet services at my…

>all of these organizations have fairly diverse tech stacks to my knowledge

>This leaves me wondering what software all these places have in common.

dunno what systems you're talking about, but seems likely they are mostly x86 systems and maybe even mostly using Intel hardware and microcode

those systems can-be/are rooted and more, to my knowledge
