   ### **Dates:** Tuesday March 10th 2026, 17:52 - 23:34 UTC ### **What happened:** The majority of iOS devices across all regions became unavailable. ### **Why it happened:** Apple's [ppq.apple.com](http://ppq.apple.com) app verification endpoint was down, causing internal device monitoring checks to fail, bringing devices offline. ### **How we fixed it:** We temporarily disabled these device monitoring checks. ### **What we are doing to prevent it from happening again:** Improved external monitoring to catch outages of apple’s [ppq.apple.com](http://ppq.apple.com) endpoint, loosened device monitoring to not take down live iOS devices if [ppq.apple.com](http://ppq.apple.com) is down.
