The "telegraphic longitude net" soon became worldwide. Transatlantic links between Europe and North America were established in 1866 and 1870. The US Navy extended observations into the West Indies and Central and South America with an additional transatlantic link from South America to Lisbon between 1874 and 1890. British, Russian and US observations created a chain from Europe through Suez, Aden, Madras, Singapore, China and Japan, to Vladivostok, thence to Saint Petersburg and back to Western Europe. Australia was connected to Singapore via Java in 1871 and the web circled the globe in 1902 with the connection of Australia and New Zealand to Canada via the All Red Line. The double determination of longitudes from east and west agreed within one second of arc (1/15 second of time, less than 30 metres).
