London Stock Exchange Goes Down Again

Outage "Only" Lasts Three and a Half Hours This Time

London Stock Exchange Goes Down Again

The London Stock Exchange (LSE) suffered another embarrassing outage on Thursday, the 26th of November. According to news reports and the LSE itself, at 1033 local time, a "connectivity issue" required the suspension of trading in all FTSE 100 Index stocks and order-driven securities. At 1400 local time, trading was able to resume.

LSE CEO Xavier Rolet was quoted as saying: "We regret the inconvenience that today's disruption to trading has caused for our clients.  Having resolved the immediate issue, we are working hard to ensure this doesn't happen again ahead of switching to MillenniumIT's trading platform next year."

On the 9th of November, a server problem caused trading to be suspended in 1 out of every 12 stocks on the LSE; there was another but different problem that caused a short outage in October as well.

Last year,  the LSE went down for seven hours.

In September, the LSE announced plans to replace its Tradelect core trading platform  with one from Sri Lanka-based MillenniumIT, which it bought for £18 million. The LSE introduced Tradelect only two years ago after spending four years and £40 million on its development.

An IBM Quantum Computer Will Soon Pass the 1,000-Qubit Mark

The Condor processor is just one quantum-computing advance slated for 2023

IBM’s Condor, the world’s first universal quantum computer with more than 1,000 qubits, is set to debut in 2023. The year is also expected to see IBM launch Heron, the first of a new flock of modular quantum processors that the company says may help it produce quantum computers with more than 4,000 qubits by 2025.

This article is part of our special report Top Tech 2023.

While quantum computers can, in theory, quickly find answers to problems that classical computers would take eons to solve, today’s quantum hardware is still short on qubits, limiting its usefulness. Entanglement and other quantum states necessary for quantum computation are infamously fragile, being susceptible to heat and other disturbances, which makes scaling up the number of qubits a huge technical challenge.
