Abstract: Techniques for the transparent rolling of nodes in a cloud-delivered headend service without disrupting client traffic or making users aware of the various nodes in the system being rolled are described herein. The techniques may include receiving an indication that a first node of a network is to be rolled. Based at least in part on the indication, new connection requests may not be sent to the first intermediate node. Additionally, a client device having an existing connection through the first node may be identified. In some examples, a request may be sent to the client device to prompt the client device to establish a new connection. After determining that the new connection has been established such that the new connection flows through a second node of the network, the first node may be rolled.
