Still, word reaches me that UBS has had to resort to quoting wide prices on its platform this week because of a problem with its data feed. “We have experienced some temporary problems following a major upgrade to our systems over the weekend. The cause of the problem has been identified and is being resolved rapidly. We have kept our clients fully informed of the situation, and we have continued to service them via traditional (non-electronic) channels during the brief periods of system unavailability,” UBS confirms. It’s funny how IT upgrades always resort in performance downgrades, at least in the short term.
