Northern Ireland’s Department of Health (DoH) temporarily halted its COVIDCert service after a data exposure incident. Some users of the service were presented with data of other users, under certain circumstances, says the Department. The service enables fully vaccinated individuals based in Northern Ireland to obtain a digital certificate confirming their COVID-19 vaccination status. Neither the web service nor the mobile app functionality is accessible at the time of writing at the moment. Both the COVIDcert website and the app endpoints are down at the the moment: “Our services aren’t available right now”””
