In order to improve validation performance and add additional resiliency to our systems, on January 18th 2017 the QuoVadis OCSP infrastructure will move to the cloud, hosted in two redundant EU regions.
This move will be transparent for most users, with no required changes. However, a small number of customer networks may have our existing OCSP IP Addresses statically set in their firewalls.
Note: QuoVadis recommends that users query DNS rather than IP Address as the services may change without warning.
The legacy IP Addresses for QuoVadis OCSP will continue to be available until January 28th 2017 but ocsp.quovadisglobal.com will no longer resolve to them.
