@thomasfuchs @Netlify I'm not aware of any issues at the moment. Are you able to access your sites directly? (on their subdomains .netlify.com)
Instinct suggests this is an issue in the config in cloudflare pointing to netlify. The best way to get support is usually via http://netlify.com/support
My tweets and posts live here on my own domain these days.
You can explore them here and follow me on Mastodon instead of Twitter where I'm not currently active.
