The disk (or server associated with it) was probably an essential part of their system. Looks like the website was up, but trades weren't going through. It looks plausible for me, so I'm not going to grab my tin foil hat for that. What else could have happened? Some people are saying some "hacker" did that, but why? And if funds are #safu, why does it matter?
paranoia from last month's hack i presume. everybody's still on their toes. i guess some people are speculating that an "intruder" in their system was detected which prompted the site being taken offline. people are probably worried that if the site is compromised again so soon, the insurance fund binance set up will have been depleted, leading to account haircuts.
i won't lie, my heart jumped a bit when i saw threads about this. it wouldn't kill me to lose what's in my binance account, but it would certainly sting.
