Where to Host My Storyline Course Modules

Greetings Folks:

I have several eLearning courses made with Articulate 360. I host these eCourses on a server. Recently, my customers have been having an issue with their courses streaming smoothly. My server has 32G of RAM, 4TB of disc space, and unlimited bandwidth along with a CDN. I'm using only 7% of all my available resources. In other words, I don't think this is a server issue but I could be wrong. What I'd like to know is if hosting these storyline course modules on my Godaddy server is a wise thing to do? Should I be hosting them on another server, perhaps a streaming server, that has a better delivery platform offering a smoother online experience? Any advice you can offer here would be most appreciated.

Thank you,
Rod Machado
