   postmortem
   ### **Dates:** Thursday June 18 2026, 03:45 UTC - 06:45 UTC. ### **What happened:** Approximately 7% of iOS devices in our EU data center were temporarily unavailable for customer test sessions after a loss of power to the rack hosting them. ### **Why it happened:** The power circuit feeding the affected rack exceeded its capacity, and a protective breaker tripped to safeguard the line - cutting power to the devices on that rack until the circuit was restored. ### **How we fixed it:** The affected circuit was reset and power restored to the rack, returning the devices to customer service. ### **What we are doing to prevent it from happening again:** We are redistributing power load across affected racks, adding capacity monitoring with early-warning alerts ahead of circuit limits, and introducing a capacity review before new devices are deployed to a rack.
