### 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 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 endpoint, loosened device monitoring to not take down live iOS devices if ppq.apple.com is down.
