A number of developers are frustrated by an increasingly problematic iCloud server issue that is causing some apps that have implemented iCloud support to not sync properly.
As in Apple's developer forums and on Twitter, there have been problems with the CloudKit connection since November. Some users of apps that have integrated iCloud support see the following message: "Request failed with http status code 503." For example, the developers of the popular note-taking app GoodNotes have observed the problem so frequently that they have created a support document for customers. written facing this error message. The GoodNotes team says that the app automatically tries to connect and this fixes the problem. However, they are not sure what is causing the connection error.
iCloud proves unreliable
HTTP 503 is a temporary error code ("Service unavailable") that indicates that the iCloud servers aren't responding properly to your device's requests. This error usually resolves when GoodNotes automatically retries, but we're receiving many reports that the error persists and causes syncing errors. This issue isn't apparent to us, and we've escalated the case to Apple Technical Support for investigation. It appears that this issue also occurs with other apps.
Some developers have found that their apps worked fine for years before the iCloud server issue that appears to be causing the error message suddenly appeared. A handful of developers were able to get help from Apple engineers, one of whom was able to modify his iCloud container for his developer account to fix the problem. But there seem to be many developers who are still affected. Other developers have integrated an iCloud status dashboard into their apps so customers can see when iCloud isn't working.
Problem could be related to iOS 15
iCloud outages are a major problem for app developers because the end user of the app is unaware that it is an Apple issue, so customers blame the app developers for a broken sync feature that is beyond their control. Several developers have reported the iCloud sync bug to Apple. However, the number of complaints and the fact that the problem seems to have been around for several months means that the problem has largely gone unnoticed. It is likely that the problem surfaced with the introduction of iOS 15 and Co. It remains unclear when a solution will be available. Users who are having problems with iCloud should therefore be aware that this is probably an Apple problem and not a bug that app developers can fix at the moment.
