Apple Services in Türkiye: DNS Steering Sends Updates, App Downloads & Music Streams to a Kyiv Edge (14–24 KB/s)
Measured 2026-07-29, Istanbul (Türksat Kablonet, 200 Mbps line). Apple has no update-CDN capacity in Türkiye, so the edge you get is chosen from your DNS resolver's egress geography. Cloudflare (1.1.1.1 / WARP / forwarders) strips EDNS Client Subnet, and Apple's geo-database mis-maps Cloudflare's egress to Ukraine — deterministically. Result: the seven bulk-transfer Apple domains below resolve to a Kyiv edge with ~13% packet loss, collapsing TCP to dial-up speed. This is loss-driven TCP collapse, not throttling — a Greek edge delivered ~186 Mbps on the same line minutes later.
Every one of these terminates on a *.g.aaplimg.com record (Apple's CDN) — the alias domain and its aaplimg record owner are list
