A fault at the London Stock Exchange prevented blue-chip British companies from trading on Friday for over an hour, the longest such outage in 8 years.
An undescribed technical issue kept FTSE 100 UKX, +0.28% and FTSE 250 MCX, +0.35% companies from opening until 9:40 a.m. local time.
The LSE described the outage as “a technical software issue.”
That’s the second outage in 14 months for the LSE LSE, +1.13% , which recently inked a $27 billion pact to buy Refinitiv, a provider of financial data and infrastructure.
The LSE’s other exchanges, including the AIM and Borsa Italiana, were operating as normal.
LSE shares rose 1.3% after the outage in a broadly better day for global markets.
This being the age of social media, Twitter had a few jokes, while the LSE itself was curiously silent on social media, with its last communication being about the need for “persuasive communication in the corporate world.”
