My phone started ringing early this morning.

“The LSE is down,” said the voice on the line.
“You’re kidding me,” I responded. “Please not today. The Fed announced the Fannie Mae and Freddie Mac rescue. Great day to be in the market.”
“Exactly. Lots of volatility.”
“Any idea of the cause?”
“Nope. It’s been called a ‘connectivity failure’ by the LSE.”

Lots of questions around this outage. I’m sure the LSE is not too happy either.

From the Wall Street Journal:

The connectivity failure by the London Stock Exchange Group PLC, the exchange operator, is an "absolute nightmare," said one trader. "We are just not trading on what should have been a big trading day."

Was it an application failure?
Was it a server crash?
Was it a network failure?
Was it a middleware issue?

We’ll get more information over the coming days, but rest assured we’re seeing the results of building complex trading ecosystems with interdependencies that have their own, often significant risk surface areas.  It's not just an LSE issue.
