I am a plebe who doesn’t understand these things but what exactly does cloudflare do? I see it popping up more and more often redirecting before visiting a site. I assume that this has something to do with bot traffic? It seems like every mention of cloudflare is about how it ruined someone’s day.
Essentially, their entire schtick is being a middleman. By sitting between the server you want to visit, they can do helpful things like DDOS protection, being a CDN (basically store website assets closer to you), managing HTTPS for you and providing access to your website over IPv6 even if your server doesn’t have it.
By nature of that though, their position is quite sensitive since it has become a service that a good chunk of the Internet goes through. That causes concerns about centralization and pisses in a lot of people’s cereals politically.
