Microsoft 365 outage causes chlorine gas poisoning at German hotel

By PulseAugur Editorial · [1 sources] ·

A Microsoft 365 outage in Germany led to 15 hotel guests suffering from chlorine gas poisoning due to a failed email-based safety alert system. The system, designed to warn operators of high chlorine levels in a sauna area, could not send notifications during the outage, resulting in elevated levels and injuries. Emergency services responded, with four individuals hospitalized. This incident highlights the risks of relying on single cloud services for critical safety functions and underscores the broader issue of corporate dependence on a few major tech providers. AI
