The London Stock Exchange’s trading failure on Friday came at a bad time for the markets but a relatively good time for its newish CEO David Schwimmer. The former Goldman Sachs Group Inc. banker has been enjoying a glorious honeymoon. It had to end at some point.

The precise cause of the outage, fixed within an hour and 40 minutes, isn’t clear. But when trading isn’t available for such a long period after the scheduled open, something has gone badly wrong. Time for an investigation.
