### \*\*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.
