Assets hosting specs

Hi, what are the specs of the hosting of assets? (where is it located?, has or supports CDN?)
I’m not sure if I should use my own hosting for the assets or the one included in squidex (I’m targeting Chilean users and I have a local hosting here, but it seems easier to use your asset manager).

Also, the pricing page does not mention the transfer of assets. Downloading an asset does count as an API call?

Thanks!

They are located in Google Cloud Storage without CDN so far.
