Sorry for not being clear, it's the Entrust Root CA I was asking about. Thank you for that link.
I did run some tests on CF8.0.1 (fully patched) running on JDK 1.6.0_45 (with the default CA Root Certs) and tried several tests from this setup and each test worked. In fact I could not even force a failed connection. So I am very certain that ColdFusion 8.0.1 with JVM 1.6.0_45 works fine even after Authorize.net disabled SSLv3. Please do not take this as a reason not to upgrade to a new version of ColdFusion. CF8 and older are no longer supported by Adode. CF9 reaches end of life at the end of 2014.
The issue our client was having on one server node in a cluster has been resolved. Another party altered the network default gateway thus the "connection failure" error we were seeing made sense.
However, the issue of having the JVM under ColdFusion potentially fall back to SSLv3 for some SSL connections (not Authorize.net of couse because you have that disabled) is still a concern that I am working on.
If others want help with ColdFusion connection to Authorize.net issues feel free to respond in here. I can usually help troubleshoot ColdFusion/JVM issues. (If the moderator doesn't mind.)
I'll update in here when I have a solution in place to prevent fallback at the JVM level.
