PROBLEM ACCESSING iTUNES STORE & SOME WEB PAGES

[starmack]

I can access the internet via Google. No problem. Ditto using Safari browser or Firefox browser.

Sometimes when I click on a page it will go to it but take forever to try and open it before it gives up and fails to open!

My worst problem is in iTunes. I can preview all music in iTunes store, including latest releases.

However when I try to enter ''Redeem'' to add credit the same issue keeps coming up t tries, on ad on, to open the page before giving up. Deeply frustrating.

My Internet Service Provider today said it was (likely) due to enhanced broadband speeds being delivered remotely to me five weeks ago???

However when he switched me back to earlier broadband access speeds nothing improved.

Deeply frustrating. Any help appreciated.

Also when I try and open some search pages in Google it seems to search endlessly for some pages and then gives up......

On Mac, what settings do I need to check ...and where. Is it proxy settings? Is it preferences?

Please please help! I sent an email to Apple support...but still heard nothing.

Have done a diagnostic on my internet set - all lights are green - connection is perfect etc etc.

Throw your suggestions at me.

Operating system is Mac 10.4.11 iTunes version is 9+

I have noticed on websites that a few people couldnt access iTunes store in past few weeks......
