How the data centres were taken out of action is secondary in the moment to the fact that they were as part of an ongoing conflict. The cloud, so often framed in abstract and borderless terms, has always had a physical home, or rather a set of physical homes in the form of data centres.<\/p>\n
These data centres, as many reading this will be all too aware, require power sources, cooling systems, easy access to water, and functioning access roads. Essentially the types of things, along with staff, that aren\u2019t easy to come by in a conflict zone.<\/p>\n
Ireland is a critical node in the global data centre network, particularly with regard to users in the European Union. While the tax breaks here obviously attracted big operators like AWS early, the mild climate has made them seek to expand. Our weather fits in the Goldilocks zone of what is needed to optimally run data centres.<\/p>\n
Ireland has also long been a key landing point for subsea cables, going back to the very beginning of the development of transatlantic communication. From long before independence and over a century since, Ireland has been central to global connectivity.<\/p>\n
Ireland benefits economically from being a connectivity hub but the risks that come with that are significant.<\/p>\n
If that doesn\u2019t scare you given the current climate then it ought to. It wouldn\u2019t take a bombardment from a nearby force to hurt that infrastructure, although we\u2019re fortunate none of our neighbours are of a mood to do so.<\/p>\n

The bar to physically damaging a data centre to a point of inoperability is much lower. Take out part of one or even a whole one and redundancy gets built in. That\u2019s what turns a potential catastrophe on a pan-European level into a minor inconvenience. It\u2019s the over-reliance on that redundancy where things get much messier.<\/p>\n
While a physical assault on a data centre located here can\u2019t be entirely ruled out, the more common method of attacking digital infrastructure is usually digital. Weaponised IT is nothing new but its strength and capability is growing. International actors know that they can launch digital attacks on these shores without ever leaving their own.<\/p>\n
In simple terms, the system works until it doesn\u2019t or someone makes sure it doesn\u2019t. Then disruptions hit quickly.<\/p>\n
In the event of an attack, and operators are capable of making the HSE hack of 2020 look like a minor scratch, the impact could be enormous. The immediate impact would be felt in Ireland and the knock-on would spread, at an alarming speed, impacting the wider EU and the global operations of companies doing business within it.<\/p>\n
