He believes that ongoing advances in communications technology mean that there is the imminent prospect that traders will no longer require data centres to be so closely situated.
To illustrate this, Rabbetts pointed to the recent advances made by American researchers by combining and mirroring two beams of light in an optical fibre to enable a signal of 400Gb/s across 12,800 kilometres.
"Even trading will be able to move to wherever it wants to be eventually, because the technology is changing. Once that technology hits the mainstream, which won't be long, then this synchronous replication - you will be able to put it anywhere virtually, so the need for it to be close to you will go away."
While he anticipates that this technology could only be a couple of years away from use, Rabbetts said that financial sector companies, which are traditionally conservative, should start to move other functions of their business to regional data centres, such as backup, disaster recovery, back office functions or any other non-critical applications.
"Financial services firms should really be looking at regional requirements now, and moving whatever they can which doesn't require synchronous replication," he said.
