Due to a critical security issue that was identified on the LetsEncrypt CA, some of our Custom CNAMEs certificates are affected and potentially will be revoked on March 4th starting 00:00 UTC (in less than one hour). To check if your hostname is affected, please visit: https://checkhost.unboundtest.com/
The affected certificates are in the process of being renewed by the CDN, and we are tracking progress.
Customers whose domain is affected and can switch to serving their traffic from res.cloudinary.com or [cloudname]-res.cloudinary.com instead of their affected custom CNAME, are encouraged to do so before 00:00 UTC March 4th. Please contact email@example.com
for assistance. As we expect high ticket load, please validate that your domain is affected, using the link above, before contacting us.
We understand this is a last-minute notification. Being a global internet security event, affecting over 3 million certificates, we will update on this issue as it unfolds and our global engineering team is on high alert to help avoid any downtime.
