- postmortem
### **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.
