Availability status for real-time payment networks

A method, comprising:

• transmitting, by a first global transaction router hosted by a first supernetwork instance, a query to a first network hub for a status of a participant system, the participant system being connected to the first network hub;
• determining, by the first global transaction router hosted by the first supernetwork instance, a participant status for the participant system based at least in part on a query response from the first network hub;
• updating, by the first global transaction router hosted by the first supernetwork instance, a participant status cache based at least in part on the participant status;
• propagating, by the first global transaction router hosted by the first supernetwork instance, the participant status to a second network hub connected to the first supernetwork instance;
• and
• propagating, by the first global transaction router hosted by the first supernetwork instance, the participant status to a second supernetwork instance connected to the first supernetwork instance.

A non-transitory, computer-readable medium, comprising a first global transaction router hosted by a first supernetwork instance, the first global transaction router comprising machine-readable instructions, when executed by a processor of a computing device, cause the computing device to at least:

• transmit a query to a first network hub for a status of a participant system, the participant system being connected to the first network hub;
• determine a participant status for the participant system based at least in part on a query response from the first network hub;
• update a participant status cache based at least in part on the participant status;
• propagate the participant status to a second network hub connected to the first supernetwork instance;
• and
• propagate the participant status to a second supernetwork instance connected to the first supernetwork instance.
