The Biggest UE4 and UNITY Asset Source you ever needed

Panda's contributions to the community are amazing but I was wondering why Panda uses uploadcloud? I guess they get some money, but why they don't use mirrors or I am missing something? I have a bad connection, just as an example: I tried to download Hospital V1.0. Estimated download time 2 days. By the way, I will wait a whole download week just to have 1950s NYC Environment Megapack. Good lord, what an asset.
