    ### 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.
