I think in the last few days, a lot of websites is down due to Cloudfare. A bit scary though, specially for us crypto enthusiast wherein time is really very important. Imagine, you trading and right at the very moment of you executing your trades, website wentdown, cursing the trading platform. LOL. Just like what we say, time is gold. It's time for Cloudfare to step up the game, otherwise they will received the blame for millions of crypto enthusiast who lost or not profit in those crucial moments. So it will be ironic to see a company that supposed to protect websites from attacks has it's own problem.
This centralization is worrying, because companies like Cloudflare can have so much power over the Internet, they can censor and disrupt the Internet on behalf of governments or other actors. Bitcoin itself is very robust and no one will be able to truly take it down ever, but a lot of its ecosystem is centralized, like the mentioned exchanges that suffered from Cloudflare's outage - if someone can cripple that ecosystem, they would also cripple Bitcoin.
