ESpanix history and evolution

ESpanix Internet Exchange Point was founded in 1997, thanks to the initiative of the Internet Users Association (Asociación de Usuarios de Internet, in Spanish). In 1998, ESpanix speed was only 10 Mbps; a tiny number compared with its current traffic. Because during its almost three decades of life, traffic has grown exponentially.

In 2002, ESpanix became the 5th European node in terms of traffic, with 4 Gbps. Four years later, in 2006, it reached 70 Gbps and went up to the third position. In 2018, ESpanix updated its trunk network and, as we mentioned before, it already exceeds 500 Gbps.
