I get "The site is under maintenance. Badges are temporarily unavailable" when I try to view my badges in Trailhead.

Also, Trailhead in general seems to be hanging.

After I created my domain and activated, I cannot log in to my developer account. It says that the server was not found. How long does it take for the domain to be registered? This is so frustrating, it says 3 minutes but it's been over 30 minutes and I have received no email and now i cannot log back into my account. Has anyone else experienced this? Any resolutions?

Just finished all of the Trails, Modules and Projects that are available up to this point using 3 different Dev Orgs. (2/3/2016)

Keep them coming. More Trails/Modules/Projects on development would be great. (Lightining,Apex,Visual Force, Javascript, Integration and using the Developer Console)

Thanks for providing these valuable resources !
