I'm not sure if that is true (and I hope it is not cause that would be fatal) but I read somewhere that with facebook being down also means all internal infrastructure of facebook isn't available at the moment (chats, communication) including remote control tools for the BGP Routers. Therefor they require people to get physical access to the router while many people are working from home cause of the pandemic.
