The main feature of a data centre that ensures there is no communication breakdown is the redundant power supply. This feature is critical because it guarantees that the data centre remains operational even in the event of a power failure. A redundant power supply typically includes backup generators and uninterruptible power supplies (UPS) to provide continuous electrical power. This redundancy helps prevent downtime caused by unexpected outages, ensuring that servers and networking equipment remain functional and communication channels stay open.

While a high-speed internet connection, cooling systems, and data integrity management are also important features of a data centre, they address different aspects of operation. A high-speed internet connection is vital for speed and efficiency in data transfer but does not specifically address the continuity of power or communication in the event of outages. Cooling systems are essential for maintaining optimal temperature and preventing overheating, which can lead to hardware failure, but they do not directly influence power supply reliability. Data integrity management focuses on ensuring the accuracy and consistency of data over its lifecycle, which is crucial for operations but does not prevent communication breakdowns caused by power issues. Therefore, the redundant power supply stands out as the key feature for maintaining continuous communication in a data centre.
