Currency trading on global markets was hit earlier today after a Reuters platform went offline.
The financial news and information provider said that its Dealing 3000 Matching platform was restored at 06:30 BST today after servers suffered outage before midnight last night.
The downtime occurred as Wellington and Sydney began their global trading, blocking movements in sterling and the Australian, New Zealand and Canadian dollars.
An American trader based in Japan told the Reuters news agency that many dealers had switched to a rival platform owned by ICAP.
"People do seem to be having some problems," he said.
"The market is a bit slow this morning for a variety of reasons, including this and the fact that the yen made some strange moves this morning."
When the platform was restored however the pound had hit a 26-year high against the dollar, trading at $2.0604.
Reuters has apologised for the outage, which did not affect trading activity in euro/dollar or dollar/yen markets.
