Release change on 24 Juli 2023 from 6 p.m. to 11 p.m.

The work is being carried out on our old CA platform. The new CA platform is not affected. 

We strive to keep any interruptions as short as possible. However, some services will not be fully available during the maintenance window. Here is a brief overview: 


  • - Changeover to the new e-mail standard "S/MIME BRG"; please note that domain validation must now also be carried out for e-mail certificates. 

  • Certificate management (issuance, revocation), MPKI Remote / CMC Interface, MPKI Web Interface and online revocation: not available. 

  • CRL: available according to SLA. 

  • OCSP, and TSA, and Signature Service: short-term interruptions possible.  

  • SwissID Sign: During the maintenance period, users cannot activate SwissID Sign via the app. Also, the above-mentioned restrictions apply to OCSP, which may affect the signature process. 


We apologize for any inconvenience caused.
