For context, see my buried comment explaining how I found this here: https://news.ycombinator.com/item?id=30906482 https://news.ycombinator.com/item?id=30906482 In summary: I don't have any indication it's in current use. I saw this URL in intercepted traffic from an iOS 13 device. I suspect it was used at some point but not anymore. I bet iOS 15 still uses something similar but doesn't use this particular URL (perhaps one with more obscurity/protection). p.s.
