Following the Steam slowdown on TelstraClear, has anyone else noticed iTunes timeouts?

Sometimes you can't access the iTune store, sometimes it will return search results but won't go to the item you select, other times it will try renting some content for a while, to then coming back with a "sorry can't complete your transaction" and suggestion there may be problems with your Internet connection?

I wonder if TelstraClear is having problems communicating over international links and causing all these slowdowns lately?
