🚦Service Notifications

 Regular Scheduled Maintenance

At ZeroSSL we use scheduled maintenance windows to perform maintenance during which certificate operations might intermittently be impaired. Maintenance windows follow these guidelines:

  • Scheduled Saturdays starting from 12 pm UTC, except for certain holidays and blackout periods
  • Last for 4 hours until 4 am UTC
  • Certificate operations are resumed once the maintenance is completed
  • ✅ It is possible to login to ZeroSSL and download existing certificates.

👉 Outside of these windows, ad-hoc maintenance might be performed for important & critical updates.

Please find updates about unplanned maintenance and other kind of service notifications below:
