Distributing user information across replicated servers

A computer-implemented method comprising:

• receiving information describing users of a system;
• storing the information describing the users across a first plurality of servers, each of the plurality of servers storing information describing a set of users;
• and
• for each server from the first plurality of servers, the server storing a first copy of information describing a set of users:
• storing a second copy of information describing the set of users across a second plurality of servers, comprising:
• distributing information describing the set of users across each of the second plurality of servers.

A computer program product having a non-transitory computer-readable storage medium storing computer-executable code for modifying a numeric value using a touch screen of a computing device, the code comprising:

• a mapping module configured to:
• receive information describing users of a system;
• store the information describing the users across a first plurality of servers, each of the plurality of servers storing a first copy of information describing a set of users;
• store a second copy of the information describing the users of the system across a second plurality of servers, comprising, for each server from the first plurality of servers:
• distribute information describing a set of users stored on the server from the first plurality across multiple servers of the second plurality of servers;
• and
• a server monitor module configured to:
• receive information describing a failure of a first server from the first plurality;
• an aggregator module configured to:
• responsive to receiving information describing the failure of a first server:
• receive a requests for information describing users stored on the first server;
• distribute the received requests across the second plurality of servers, comprising, for each request for information describing a user:
• identify a second server from the second plurality of servers storing the second copy of information describing the second user;
• and
• send the request for information to the second server.
