Abstract: Techniques are disclosed for transmitting a message to a user device in accordance with a determination that another device is unreachable over a network. In one example, a server device, at a first location, may identify a controller device resident at a second location, whereby the controller device is configured to communicate with a router at the second location. The server device may also receive a list of user devices. The server device may transmit a ping message to the controller device via the router to determine whether the controller device is unreachable by the server device. The server device may subsequently transmit a message to a user device on the list in accordance with a determination that the controller device is unreachable by the server device, whereby the message includes instructions for the user device to determine whether the controller device is unreachable by the user device.

Abstract: A device implementing a system for proxying data between devices includes a processor configured to obtain a first latency and a second latency, the first latency being between a server and a first subnet, and the second latency being between the server and a second subnet. The at least one processor is further configured to train a machine learning model with a training dataset that includes the first latency with respect to the server and the first subnet, the second latency with respect to the server and the second subnet, and geographic data of the server, the first subnet and the second subnet. The at least one processor is further configured to use the machine learning model to estimate a third latency between the server and a third subnet, and store the first, second and third latencies in a data structure.

Abstract: Aspects of the subject technology provide for privacy-preserving electronic publication and subscription. A publisher device may establish a publication channel with a publication server and receive a channel identifier and a channel ownership token for the channel. The publisher device may provide the channel identifier and a key for the publication channel to a subscriber device. The publisher device may publish data encrypted using the key to the publication server, the subscriber device may obtain the encrypted published data from the server using the channel identifier, and may decrypt the published data using the key obtained from the publisher device. The published data may include status information for a user of the publisher device, in some examples.
