What to Know

To prepare your business for readiness,

• Please plan to be unable to submit orders, accept orders, check order status or issue/fulfill orders.
• We will transition data center (DC) operations for our GeoTrust, RapidSSL, Symantec, Thawte, Managed PKI for SSL, and Encryption Everywhere product lines over to our DigiCert DC.
• We will upgrade software at multiple points in our infrastructure, resulting in improved performance and compliance but diminished operational risk.
• You will have no access to certificate ordering, order checking, and fulfillment services, nor will your customers and/or subresellers (as applicable).
• Our APIs will return HTTP 404 return codes.
• Routine order processing for GeoTrust, RapidSSL, Symantec and Thawte branded certificates will be paused. Once the maintenance concludes, we will resume orderly processing of those orders, prioritizing orders submitted before the maintenance begins.
• IP addresses for our services will be updated. Please refer to https://knowledge.digicert.com/alerts/ip-address-changes-by-system-maintenance-coming-in-april-2019.html for details.
• Our seal services and revocation validation services (CRL and OCSP) will continue to operate normally.
• Current/existing certificates and our trusted seals will function without disruption.
• We will have processes in place during the downtime to handle emergency revocations.

Your planning and preparation will minimize impact to your revenue generation and support operations.
