As a precautionary measure, and in order to prevent potential damage to your equipment, we strongly recommend that you send personnel to the Rennes facility as soon as possible to perform an orderly shutdown of your equipment. Given the current conditions, leaving the systems powered on may expose them to a significant risk of overheating and hardware damage.

Below is the weather forecast for June 22, 2026.”
