The downtime began at around 9am UK time on Wednesday, and has continued to affect various Apple services, including the iTunes Store and the App Store.
This of course means buying music and downloading apps isn't currently possible, nor is accessing the iBooks Store. The Mac App Store is also down.
The iTunes Store brought $2.6 billion in sales in the last quarter of 2014, bringing in around $1.17m in sales an hour. That makes an 8-hour and counting outage very costly indeed.
Temporary outages aren't entirely abnormal but a prolonged period offline for Apple's stores is much rarer.
So if you're having issues with the aforementioned Apple services, fear not - you're not alone.
