Rate limits for frequent iOS resets (EraseDevice) and activation processes?
Hello everyone, I am looking for technical clarification regarding potential rate limits when automating frequent iOS device resets. In my workflow, I need to reset test devices multiple times per day using the EraseDevice MDM command, often combined with the ReturnToService flag for automated setup. I understand that after a full reset, the device undertakes several critical steps to become operational again, including device activation, system app installation, MDM re-enrollment, and subsequent validation of developer certificates for internally distributed apps. Based on Apple’s documentation and my own observations, I am aware of the following domains being involved in these processes: Device Activation: albert.apple.com, gs.apple.com, captive.apple.com, humb.apple.com, static.ips.apple.com, sq-device.apple.com, tbsc.apple.com, time*.apple.com System App Installation: *.itunes.apple.com, *.apps.apple.com, *.mzstatic.com MDM Enrollment: Communication with Apple ADE servers followed by the MDM server. Developer Certificate Validation: ppq.apple.com, ocsp.apple.com, crl.apple.com My primary question is: Are there any rate limits imposed by Apple’s servers on these specific processes when performed frequently on the exact same device within a short timeframe (e.g., multiple times per day)? Specifically, could anyone provide information regarding potential limits for: Device activation requests? System app downloads post-activation? Automated Device Enrollment checks and subsequent MDM enrollments? Developer certificate validation requests? Additionally, is the list of domains above comprehensive for these processes, or are there other key endpoints involved that I should be aware of regarding potential rate limiting? Understanding these limitations is crucial for ensuring the reliability of automated device management workflows. Thank you for any insights!
