"Your account is temporarily unavailable."

Ditto Jeannif, also in the UK

This is weird I can get apps on my iPhone but not my iPad, what on earths going on....

Mine is crazy too I can get apps on my iPod but not on my iPhone?! Also in the UK. CRAYCRAY!

This is weird, I went to my account info, and where it says the credit card stuff, it says "No credit card on file" or something like that, is anyone else getting that? I can't get any apps on my laptop, and im getting an iphone tonight, so I'm hoping itll be fixed by then...

I am currently experiecing the same thing, and when I try access the iTunes or App Store from my iPad it just won't load anything.

It seems to be working again now.

Was able to upgrade an app, but attempts to restore iTunes Match still giving me the same response, so not fully functional as yet. iCloud is still an issue.

Same problem😠

This is driving me nuts......still getting same message, tried to contact support was told to email and I'd get a reply within 24 hours, that's useless. I WANT AN ANSWER NOW!!!

Relax, at least they are doing something to protect us (I hope). I've been waiting for an adjustment since sending an email 3 days ago, but it can wait vs. this stuff. They will fix it.

This also points out why I am sick of too much of this technology. Too easy to do things (worked in tech security, beleive me it is). No more cell phones that connect to internet for me, I am almost at that point. Too much anxiety in today's world!

Almost everybody noticed Apple's issues last night and this morning. Apple was tightening their security policies and changing how iCloud and iTunes security works in response to the very public Mat Honan hack:

Both Apple and Amazon changed their security yesterday in response to the hack. I think that Google is about to enforce security changes as well to encourage users to use two-factor authentication.

If your account doesn't already work normally, it should again soon. I noticed both of my accounts were working normally (backups, restores, app downloads, account info) this morning.

same problem

Mine isn't working yet here in Nevada. I'm still locked out on all devices; iPhone 4S, iPod Touch, iPad 2, and my PC. I don't even want to try calling Apple Care, as it's probably a major cluster right now. Any one else up and running yet?

Okay, it works on my iPod Touch but nothing else still, including my PC. I'm afraid to sync my iPod Touch in case it get scrambled, but what if that would solve the problems with my other iDevices?

I am in Chicago. As of yesterday at around 7 pm CST, my iTunes on my MacPro at home displayed this problem. My iPhone can update the apps, though. I checked on my iTunes this morning at 8 am CST, but it still displayed the same problem. My iPhone can still update.
