Some upgraders are reporting issues trying to install the iOS 7 update, as well as access to iTunes. It’s unclear how widespread the issue is.

Affected users are reporting that the downloads will stop, with a warning error pop-up that says the “software update failed.” Others are saying they cannot connect to the iTunes Store to update apps.

The likely culprit is that Apple’s servers, which are pushing out the update over the air as well as through iTunes, are being hit by many users attempting to get the download. Nonetheless, according to Apple’s service’s page, all is various services are up and running.
