ABOUTInternet Exchange Points (IXes or IXPs) are physical places where infrastructure companies interconnect with each other to exchange data destined for their respective networks. These locations are critical for companies to shorten their connection paths to other network participant, this allows for reduced round-trip time and low latency. Wikipedia ↗︎
