If you're an iOS or Mac user, your downloads and streams are going to improve in the near future -- if they haven't already. Apple has quietly switched on its own content delivery network (CDN), letting it deliver files directly instead of leaning on services from Akamai and Level 3. The change gives the folks in Cupertino a ton of headroom, according to Frost & Sullivan analyst Dan Rayburn. In addition to offering "multiple terabits per second" of bandwidth, Apple has clearly struck Netflix-like connection deals that link it directly to internet providers. If all goes well, you should get speedy app updates and media streams even when the internet is extra-busy.
