1. A method comprising:
generating, by a computing device, a first communication tunnel to a first tunnel endpoint;
determining, based on receiving a response to a transmission, that the first tunnel endpoint is available, wherein the transmission is configured to generate and traverse within the first communication tunnel; and
routing, based on the first tunnel endpoint being available, network traffic to the first tunnel endpoint.
