DigiCert 2021 maintenance schedule

Maintenance schedule applies to all DigiCert platforms and solutions

To make it easier to plan your certificate-related tasks, here is our 2021 maintenance schedule.

This page is kept up to date with all maintenance schedule information.

QuoVadis CA systems: The DigiCert 2021 maintenance schedule does not affect the QuoVadis CA systems. Maintenance for these systems is done via a different maintenance schedule.

Why does DigiCert schedule maintenance windows?

DigiCert uses scheduled maintenance windows to perform maintenance with potential to interrupt DigiCert services.

Maintenance windows follow these guidelines:

  • Scheduled for the first weekend of each month, except for certain holidays and blackout periods
  • Last for 2 hours
  • Normal operations are resumed once maintenance is completed

What can I except to happen during scheduled maintenance?

Although we have redundancies in place to protect your services, some DigiCert services may be unavailable:

  • Console and API access
  • Certificate validation
  • Certificate issuance
  • Websites (for example, digicert.com)

Services are restored as soon as the maintenance is completed.

What can I do?

Please plan your certificate-related tasks accordingly.

  • Schedule high-priority orders, renewals, reissues, and duplicate issues outside of the maintenance window.
  • If you use the API for immediate certificate issuance and automated tasks, expect interruptions during each maintenance window.

For live updates, subscribe to the DigiCert Status page.

If you need more information regarding these maintenance windows, contact your account manager or DigiCert support team.
