Expediting correction of WAN or LAN traffic loss

A system comprising:

• a memory;
• and
• one or more processors that are configured to execute machine readable instructions stored in the memory to perform operations comprising:
• determining a shortest time interval heartbeat sub-set of at least two types of heartbeat traffic detected between a first gateway device and a second gateway device, wherein:
• the first gateway device is communicatively connected to the second gateway device via a virtual uplink over a local area network (LAN) connection, and
• the at least two types of heartbeat traffic in the shortest time interval heartbeat sub-set have shortest time intervals between heartbeats among types of heartbeat traffic detected between the first gateway device and the second gateway device;
• determining that heartbeat responses from the second gateway device to the first gateway device are missing for both of the at least two types of heartbeat traffic in the shortest time interval heartbeat sub-set;
• and
• suspending the virtual uplink between the first gateway device and the second gateway device.

A non-transitory computer-readable storage medium storing a plurality of instructions executable by one or more processors, the plurality of instructions when executed by the one or more processors cause the one or more processors to perform operations comprising:

• determining a shortest time interval heartbeat sub-set of at least two types of heartbeat traffic detected between a first gateway device and a second gateway device, wherein:
• the first gateway device is communicatively connected to the second gateway device via a virtual uplink over a local area network (LAN) connection, and
• the at least two types of heartbeat traffic in the shortest time interval heartbeat sub-set have shortest time intervals between heartbeats among types of heartbeat traffic detected between the first gateway device and the second gateway device;
• determining that heartbeat responses from the second gateway device to the first gateway device are missing for both of the at least two types of heartbeat traffic in the shortest time interval heartbeat sub-set;
• and
• suspending the virtual uplink between the first gateway device and the second gateway device.
