LONDON - AboveNet, a leading provider of fibre optic connectivity solutions for
business and carriers, today announced an agreement with multilateral trading
facility Chi-X Europe. This agreement will provide financial institutions
with ultra-low latency connectivity and proximity hosting for accessing Chi-X
