Facebook blames 'server config change' for 14-hour outage. Someone run that through the universal liar translator


Testing is difficult at scale

I remember an article about WhatsApp (before it was acquired).

They said they can't really do any serious load-testing. What they ended up doing was to fade-in chances on a server-by-server basis and see how it played out.

WhatsApp had very few servers back then, even though it had 900 million users.

That said, because of the lack of a FB account, I couldn't care less about their outages. The sooner they go away, the better for humanity.
