Videsh Sanchar Bhavan at No. 4 Swami Sivananda Salai is the building that carried India's international voice and data traffic out of Chennai, and it still concentrates the city's peering. Five exchanges reach it - DE-CIX Chennai, Extreme IX Chennai, NIXI Chennai, MX-IX Chennai and REDIX Chennai - and between 43 and 81 networks are recorded there, the building being carried under two names that resolve to the same address. Control moved on 19 October 2016, when ST Telemedia completed its purchase of 74 per cent of the Indian data centre business; STT Global Data Centres India runs the building today as STT Chennai 1, with Tata Communications holding the remaining 26 per cent. NIXI's own facility entry gives its address as care of STT at Videsh Sanchar Bhavan, Chennai 600002.
