The vulnerability of Britain's digital service system is due to its dependence on a few cloud providers, Google, has had a server incident at the Dalles data center in Oregon, USA. A technician diagnosed an excessively high CPU temperature. The consequences of this event were not limited to Dalles but involved other Google data centers in Europe, such as the one in Reggio Emilia, Italy.

These events have caused significant problems for many British companies, including Royal Mail, Revolut, HSBC, and Lloyds Bank. In particular, the incident has led to issues with NHS apps, Roblox, and Signal, and has affected smart mattresses globally. The events occurred about 15 hours ago when Google's data and operations were managed by Amazon Web Services (AWS) in Virginia, where there was more density of data centers.

This caused a wave of problems that hit various applications, including Roblox, Signal service, and smart mattresses. The problem is due to the increasing dependency on larger cloud providers, such as Google, AWS, and Microsoft Azure, which contain most of the available cloud service options. These providers have become 'hyperscalers' because they have grown so large that they are considered 'too big to fail'.

Hyperscalers have a growing dependence on the infrastructure supporting their activities, often poor and unreliable, that sustains their business. This dependence can be a threat to the security and resilience of digital service systems. An example of this situation is represented by the Google incident, which has shown the need to improve the security and resilience of our digital service systems.

The solution could include the creation of a data backup system and the construction of high-quality new data centers. Finally, it is important to remember that not only Google or other cloud providers need to face these problems. However, the responsibility for protecting our digital service systems lies with all users and companies that use these cloud service platforms.
