### Dates:
Wednesday, March 19 2026, 04:45 UTC - 10:47 UTC.
### What happened:
Approximately 15% of iOS devices in our US-West data center were temporarily unavailable for customer test sessions due to failed internet connectivity checks.
### Why it happened:
An automated wireless network optimization feature adjusted transmit power levels on access points serving the affected devices, degrading wireless connectivity and causing devices to fail their availability checks.
### How we fixed it:
The affected access points were identified and restarted, restoring normal wireless connectivity.
### What we are doing to prevent it from happening again:
Evaluation of the automated optimization tools and a monitoring improvement.
