Pursuant to the California Elections Code section 19205, “no part of a voting system shall be connected to the internet at any time, or electronically receive or transmit election data through any exterior communications network.” The voting systems used in California, including the one used in San Bernardino County, do not connect to the internet.
San Bernardino County uses an air-gapped system in its ballot tabulation rooms, meaning the ballot counting equipment is never connected to the internet and is completely separated from any other network. There are no routers connected to the tabulation system and there never have been.
