I had a similar experience landing in Ohaire Airport. We changed from a landing approach to a rapid vertical climb. All the power went out at the airport and there was no Air Traffic Control or any runway lights. The pilot decided the safest place to go was straight up.
We had to divert to a different airport. They apologized for the inconvenience. We were just glad to be alive.
This apparently happened before DIE was the prescribed manner for the approach. 🙂
