For the last few hours iTunes servers have been excruciatingly slow, causing delays and missing ranks for some countries. We’ve been investigating this issue since the early morning and, unfortunately, the problem lies with iTunes and is out of our control.
What’s going on with the iTunes servers?
While investigating the ranks issue we also noticed that app reviews are just as messed up. They seem to disappear randomly and then show up again (You can see this for yourself by browsing through iTunes). We can only assume that Apple is performing some unannounced maintenance on their servers, and hope that they’ll be back to normal soon.
When will this issue clear up?
We can’t say for sure since the issue is on Apple’s side. We’re keeping an eye on the situation and will post updates as soon as we have more information.
