1. A method for performing disaster recovery across a plurality of geographically dispersed nodes, the method comprising:
recording an order that each of a plurality of nodes is established in one or more databases stored with each of the plurality of nodes;
designating, based on the recorded order that each of the plurality of nodes is established, a first node to be established as an alpha node and designating the remaining nodes as beta nodes;
receiving by the alpha node, periodically, from each of the beta nodes, a status signal;
determining, by the alpha node, that a beta node did not send a status signal; and
in response to determining that the beta node did not send the status signal:
performing actions, by the alpha node, to attempt to restore the beta node;
notifying a user when the actions do not restore the beta node;
updating the order, wherein the updated order does not include the beta node; and
sending by the alpha node, to each of the remaining nodes an acknowledgement signal which includes the updated order, wherein each of the remaining beta nodes stores the updated order.
