Today, Autodesk will perform an upgrade to a security protocol that will enhance our ability to provide secure access to Desktop Subscription software. The upgrade is in response to published information describing a vulnerability in SSL 3.0, a communication protocol designed to provide security over computer networks. The vulnerability, called POODLE, is an industry-wide vulnerability and is affecting the SSL 3.0 protocol itself and is not specific to Autodesk products.
For Revit users specifically, you may have other issues connecting to A360 in Revit, as well as accessing a number of cloud services.
