The service disruption is due to an overhead line issue, a spokesperson for the Irish Rail said in a statement, adding that the staff are currently working to resolve the issue. Services currently remain suspended between Lansdowne Road and Dún Laoghaire in Co Dublin. Meanwhile, the Dart services, which are currently operating, are between Greystones/Bray and Dún Laoghaire, as well as Lansdowne Road and Howth/Malahide.
On July 29, 2025, enterprises relying on Microsoft Azure's East US region experienced an unexpected disruption that reverberated across numerous organizations. The root cause wasn't a network breach, misconfiguration, or other complex technical mishap. It was something shockingly basic: a lack of capacity.
The Microsoft outage that disrupted Teams, Exchange Online, and related services was ultimately caused by an overly aggressive traffic management update that unintentionally rerouted and choked legitimate service traffic.
MTA spokesman Tim Minton said later: "While the investigation into cause is in its early stages, this appears to be an equipment issue limited to a small area inside the station complex that caused limited service disruption."
