Q: Nothing will download off the iTunes/App Store

Try this:

1: Launch the Settings app, scroll down and tap on iTunes & App Store.

2: Tap on your Apple ID, and select the ‘Sign Out’ option from the pop-up menu.

3: Type the password to your Apple ID to login again.

No problem with Apple servers  >   Apple - Support - System Status

Try a reset. Tap Settings > General > Reset > Reset All Settings then restart he device then try downloading content from the iTunes or App Stores.

If that doesn't help, tap Settings > General > Reset > Reset Network Settings. You will have to re enter your Wi-Fi password then try a download again.

Have the same problem as noahrl. Tried what has been suggested but nothing worked

i can confirm the problem, originating from today, aug 08-27-2015. yesterday, all had been fine.

updates for apps in itunes or on mobile devices come in at speeds between 150 kB/s or even 20 kB/s only. no way!

internet is fine, all apps working, speed test states full usual download and upload rate. router monitoring tells me that there is no action in background going on.

i also notice that itunes asks me to type in my apple id password every single time i open it.

this is via wlan and lan, for all my devices: black macpro early 2014 and macbook early 2011 (both macos 10.9.5, itunes 12.2.2.25), ipad mini retina and iphone 6 plus (both 8.4.1).

anybody got an idea?

thank you!

update:

problem still going on. even worse now: max download speed 25 kB/s all the time... 

I have the same problem. Tried with different providers: cable, DSL, LTE. All connections are fine, just downloading form iTunes is extremely slow.

today everything back to normal.

had a call with apple. they say they do not know anything about it.

and it is slow again.

since this is definitely on apple's end - why don't they tell us what's wrong?

Since a few days it works again. Transfer rate is normal like before.

back to normal last 3 days. keep fingers crossed.

Sounds good. Let us know if the issue occurs again.

Same problem here.
