• To prepare for the expected surge in communication volume due to mass rallies for and against the impeachment scheduled on Friday (04 April), the telecommunications companies are deploying additional mobile base stations and are coordinating with the Korean National Police Agency regarding the safety of personnel on-site. They have already deployed additional mobile and temporary base stations near Gwanghwamun and Anguk Station to respond to previous rallies.
• Major commercial banks in Korea will temporarily close their branches near the Constitutional Court on Friday (04 April). The banks made this decision due to concerns over potential safety incidents, as large crowds of supporters and opponents of impeachment are expected to gather near the court.
