Critical Infrastructure Disruption in Denmark on May 04 2018 04:19 AM (UTC).
Parts of southern Copenhagen were left without power for around two hours on Thursday morning. The blackout, which began at around 11am and was resolved by 1pm, was reportedly caused by an outage at a substation. 30,000 people in the city were affected, supplier Radius Elnet confirmed via its Twitter account. As well as Copenhagen S, some parts of neighbouring district Amager were also affected, according to residents who posted updates on the social media site. "We are looking into the problem, which appears to have been caused by the shorting out of a substation," Radius Elnet press spokesperson Morten Kidal said earlier on Thursday.
