Upcoming Scheduled Maintenance

DigiCert will perform scheduled maintenance on February 12, 2022, between 22:00 – 24:00 MST (February 13, 2022, between 05:00 – 07:00 UTC). Although we have redundancies to protect your services, some DigiCert services may be unavailable during this time.

What can I do?

Plan accordingly:

• Schedule high-priority orders, renewals, and reissues before or after the maintenance window.
• If you use the APIs for immediate certificate issuance and automated tasks, expect interruptions.
• To get live maintenance updates, subscribe to the DigiCert Status page. This subscription includes email alerts for when maintenance begins and when it ends.
• For scheduled maintenance dates and times, see DigiCert 2022 scheduled maintenance.

Services will be restored as soon as we complete the maintenance.

Expanding Range of IP Addresses Used for DigiCert Services

As part of our scheduled maintenance on February 12, 2022, 22:00 – 24:00 MST (February 13, 2022, 05:00 - 07:00 UTC), DigiCert is expanding the range of IP addresses we use for our services. These additional IP addresses are part of our efforts to increase service uptime and reduce the need for service downtime during scheduled maintenance.

What do I need to do?

If your company uses allowlists*, update them to include the block of IP addresses listed below by February 12, 2022, to keep your DigiCert services and API integrations running as expected.

*Note: Allowlists are lists for firewalls that only allow specified IP addresses to perform certain tasks or connect to your system.

New range of IP addresses

Add this range of IP addresses to your allowlist: 216.168.240.0/20

Note: We are not replacing or removing any IP addresses. We are only expanding the range of IP Addresses we use to deliver our services.
