Systems, methods, and devices related to estimating backhaul quality, detecting Internet connectivity, and managing server load are described herein. In some aspects, a wireless device is configured to determine a characteristic of an active communication link. The device includes a processor configured to determine an allowability for accessing a server, via the active communication link, based on a first access restriction. The device further includes a transmitter configured to transmit a request for a communication from the server upon allowability for accessing. The device further includes a receiver configured to receive the communication from the server, over the communication link, in response to the request. The processor is further configured to determine a characteristic of the communication link based on the communication from the server. |
