Disaster Recovery Blunder Broke New York Stock Exchange This Week
The Register, January 26th, 2023
On Tuesday, the New York Stock Exchange (NYSE) failed to open properly, disrupting and invalidating auction trading for more than 250 securities.
The NYSE in a statement on Wednesday said that "a technical issue" prevented the opening auction process by which stocks get priced through the reconciliation of orders since the previous day's market close.
"The root cause was determined to be a manual error involving the exchange's disaster recovery configuration at system start of day," the NYSE said.
