Discord is entirely down right now, both the website and the app itself. Amusingly, a lot of the sites that normally track outages are also down, which made me think it was my internet at first. Downdetector, monitortheinternet, etc.
Lots of other big sites that are down: Patreon, npmjs, DigitalOcean, Coinbase, Zendesk, Medium, GitLab (502), Fiverr, Upwork, Udemy
Edit: 15 min later, looks like things are starting to come back up
Kudos to the people at Discord. Just a few minutes after I got disconnected they already tweeted about the issue. Some minutes later and they have a message in their desktop app confirming it's an issue with Cloudflare. All while Cloudflare's statuspage says there are 'minor outages'.
I'm hoping someone can answer a question to which I've never heard a really satisfactory answer: Why does human health benefit from exercise whereas any kind of simple machine wears out with exercise? For example, doing a hundred stretches per day improves my health whereas stretching an elastic band 100 times per day will cause it to lose elasticity and soon destroy it. So what's the low-level mechanism by which exercise improves health in people but not in simple machines?
