When did you perform that verification? I know they started out by hosting storage chunks on AWS and Azure in 2011, but they have massively increased their own data center capacity since then.
And "how" was it verified? When Apple was building a large datacenter in North Carolina[1], a lot of local techies were saying it was for 2 purposes -- Siri and iCloud. Granted, that was the popular technology at the time for Apple, so it may have been inferred knowledge, and not directly stated...
I also wouldn't be surprised if they used AWS/Azure for load balancing, geodns, routing and simple filtering before actually being tunneled in to their datacenter.
