The spate of hot weather in the UK claimed a notable scalp after a London datacentre experienced a cooling failure, which caused several servers to overheat and crash.

The Braham Street data centre, located in the City of London, and owned by Level 3 Communications, experienced a chiller failure on Sunday when one of the five units designed to cool the data centre failed.

"On 31 May, we experienced a problem with one of the five chillers in place at the site," said James Heard, President of the European markets group, in an official statement from Level 3.

"The faulty chiller is currently being repaired, and the other chillers continue to operate at the facility," he added. "Customers are being informed of the issue."

It is understood that the datacentre itself continued to run as usual with no downtime, but that several servers within the datacentre itself overheated and crashed.

Although the outside temperature on Sunday in that area peaked at a high of 23 degrees Celsius, the internal temperatures within the data centre soared to an estimated 50°C by 7pm in the evening. Typically, datacentres aim to run at anywhere from 18°C to 25°C.

These soaring temperatures claimed at least one victim, bringing down servers belonging to the music service Last.fm, for five hours approximately.
