McKay Brothers International Launches Lowest Known Latency Microwave Routes From Interxion London

MCKAY BROTHERS INTERNATIONAL LAUNCHES LOWEST KNOWN LATENCY MICROWAVE ROUTES FROM INTERXION LONDON

London, UK, 23 June 2015 INTERXION HOLDING NV (NYSE: INXN), a leading European provider of cloud- and carrier-neutral colocation data centre services, today announced that McKay Brothers International has chosen Interxion’s Central London data centre campus to deploy the lowest known latency connections between the City of London & Slough and the City of London & Frankfurt.

By colocating at the Interxion London Campus and cross connecting to McKay Brothers European network, trading firms and market makers can all equally benefit from microwave and millimetre wave links to key European Financial centres and thereby achieve better risk management and trading.

McKay Brothers is the leading low latency microwave network provider and already runs well-established US microwave networks between Illinois and New Jersey, as well as millimetre metro networks within those key states. Microwave typically offers a better-than 40 per cent improvement in latency over fibre connections.

McKay Brothers has launched two products in the UK based on its microwave technology. The first is a private wireless bandwidth product, and the second is the Quincy Extreme Data service, which distributes select European and US market data to subscribers at the lowest known latency. McKay Brothers publishes latencies for all its routes on its website.

François Tyč, managing director, McKay Brothers International, comments: “Our market-leading microwave technology provides extreme low latency connectivity to help our customers manage risk more effectively and execute on strategies. We connect locations that matter to our clients, and we know that the link between Interxion’s London data centre and Frankfurt is one of the single most important in Europe. Many of Europe’s leading financial services companies are situated in Interxion’s data centres, and we are excited to offer reliable, extreme low latency services to this new and growing market.”

William Fenick, strategy and marketing director, financial services, Interxion, comments: “McKay Brothers’ range of product offerings is democratising financial services and making the benefits of low latency available to all. As the leader in microwave technology, McKay Brothers has an established track record of excellence and reliability, and its technology will create significant added value for both new and existing financial services customers in Interxion’s London data centre to help them stay ahead in a dynamic and ultra-competitive market.”
