I like that it serves up my website at all times, regardless of where users are located (even if they're not connected to our internet).
It's quite easy for me as well since we don't have any special tech knowledge required or even needed - just upload your files/content into their system once you've signed up. The only downside about this service overall would be its price point with monthly costs being very high compared to other CDNs out there. We use them primarily because of how simple it was set up from an admin perspective when uploading media assets such as images which help us get more traffic.
