Ireland and Britain conduct first subsea telecoms cable security exercise

While disruption to one cable has been described as not being detrimental to telecoms services — given the resilience in the system and the availability of sister cables — an attack on multiple cables at the same time could have a serious impact. File picture

Ireland and Britain are examining the results of the first-ever joint exercise simulating disruption to “multiple communication cables” in the Dublin region.

The test was described as a “realistic scenario” affecting sub-sea telecoms cables connecting the two countries. There are an estimated six digital cables landing in the Dublin region that connect to Britain over the Irish Sea.
