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.
