Question about the "ALL" CDN in Traffic Ops

[Jifeng Yang (jifyang)]

Hi,

I noticed that a CDN named “ALL” was added in Traffic Ops since Traffic Control 
2.1.

I wonder the reason for adding the “ALL” CDN (what’s the purpose of adding it). 
Would it cause any issue if I remove the “ALL” CDN in my deployment?

Thanks,
Jifeng
