App Store Connect Hit by Performance Degradation This Morning

What You Need to Know
- App Store Connect experienced performance degradation starting 9:00 a.m. ET affecting some developers.
- The outage impacted multiple platform areas including builds, TestFlight, analytics, and app submission workflows.
- Mac App Store sign-in issue occurred earlier the same morning but was resolved quickly.
- Apple provided no specific timeline or breakdown of affected components beyond “performance issue” classification.
App Store Connect ran into performance problems this morning, with Apple’s developer platform showing degraded service starting at 9:00 a.m. ET. Apple confirmed the issue on its Developer System Status page, describing it as a performance problem affecting some users, without specifying which parts of the platform are involved.
The scope matters more than the label. Developers use App Store Connect to upload builds, manage app listings and personalized collections, run TestFlight, check analytics, and submit updates for review. A partial outage can stall any of those workflows, and the timing is unpredictable enough that developers mid-submission have no clean workaround.
Reports on X suggest the issue touches more than one area of the platform, which is consistent with a general performance degradation rather than a single broken endpoint. Apple has not broken down the affected components beyond the broad “performance issue” classification.
A Second Issue Resolved Earlier
The App Store Connect outage was not the only problem Apple’s infrastructure logged today. The System Status page also flagged a Mac App Store sign-in issue earlier, though Apple marked that one resolved shortly after it appeared. Two separate status entries in one morning is unusual, even if neither individually looks catastrophic on paper.
For developers on Apple Silicon who rely on running iPhone apps on Mac through the Mac App Store, a sign-in disruption on top of an App Store Connect slowdown compounds the friction. Apple has not offered a timeline for resolution on the Connect side. The Developer System Status page remains the only place Apple is communicating updates, so checking it directly is the most reliable option until the issue clears.
