Coding curriculum not loading

For last two days, My coding curriculum is not loading.
the link is here:
https://learn.freecodecamp.org/front-end-libraries/react/bind-this-to-a-class-method
I am using Chrome on Windows 10. I have also tried microsoft edge. What I have noticed is that the “learn” subdomain is not working.
Thanks
