GitHub Down? Throwing HTTP 500 (github.com)

This appears to be affecting Chrome 69. Runs fine in Firefox. Dev console throws: "Refused to load the font '<URL>' because it violates the following Content Security Policy directive: "default-src 'self'". Note that 'font-src' was not explicitly set, so 'default-src' is used as a fallback."

Also doesn't work on Safari

First time I've ever seen the Github 500 error page. It looks cool!

Appears to be online now.
