Due to scheduled maintenance, the use of ID-cards, Mobile-ID, and Smart-ID in e-services will be briefly unavailable


SK ID Solutions, the partner of the Estonian state in certification and time-stamping services, will be carrying out scheduled maintenance in its information system from 11 p.m. on 28 May to 5 a.m. on 29 May. Due to the maintenance works, the use of Mobile-ID and Smart-ID as well as time-stamping and validity confirmation services and giving digital signatures will be unavailable from 2 a.m. on 29 May.

‘To ensure that the maintenance works disturb users as little as possible, SK ID Solutions updates its systems at night. There may be disruptions in the use of ID-cards, Mobile-ID, and Smart-ID starting from 11 p.m. on 28 May. Starting from 2 a.m. on 29 May, Mobile-ID and Smart-ID solutions will be unavailable for a few hours and ID-cards can only be used for authentication in certain services. During this time, digital signatures cannot be given in e-services or the DigiDoc4 software and the time-stamping and validity confirmation services will be temporarily suspended,’ said Margus Arm, Director of the State Information System. ‘Unfortunately, Estonians who are staying abroad must take into consideration that the service interruption may not take place at night for them. Therefore, important operations related to signing and authentication should be rescheduled to an earlier time,’ he added.

During the service interruption, the ID-card can be used for authentication in services that have joined the state authentication service provided by the Information System Authority (RIA). If maintenance works are carried out without issues, all services will be restored by 5 a.m. on 29 May. If maintenance works take longer than planned, use of the data exchange layer X-tee may also be interrupted, due to which data exchange between different information systems may be unavailable.

‘SK has carried out several tests and assessed the risks related to the update, based on which the duration of the interruption should not exceed two hours. By the morning, all the affected services should be functional again. However, we cannot plan for everything, so we must consider the possibility that interruptions will continue to occur throughout the morning and day of 29 May. If this does happen, please contact the provider of the e-service where the disruption occurred,’ Margus Arm said.

ID-card as a loyalty card is not affected.

From 11 p.m. to 1 a.m., short interruptions of up to 30 minutes may occur in all services of SK ID Solutions. From 2 a.m. to 5 a.m., all services of SK will be interrupted for up to two hours, including:

  • using Smart-ID;
  • using Mobile-ID in Estonia and Lithuania;
  • validity confirmation services (OCSP);
  • the time-stamping service;
  • using ID-cards;
  • issuing ID-cards and Digi-ID and changing the statuses of certificates;
  • issuing Mobile-ID (Estonia and Lithuania) and changing the statuses of certificates;
  • issuing and cancelling Smart-ID.
