Where is the back up? Heads should roll

Clearly the problem stems from writing a finance-related application in something other than VBA-running-inside-Excel. "Linux"... what will they think of next!?

(I'm being sarcastic, but people say stuff like this every day and aren't. That's what's scary.)

There's a lot of ignorance going on in the articles out there. I know nothing of the internals of the project but it was commissioned to replace a system that has frequent outages (including a major one last week). Teething issues, while not desirable, are inevitable at such an early stage of the project. It's bound to be an incredibly complicated system.

I feel for the devs working on it. Bet they didn't have a fun morning....

Does this same logic apply to, say, a control module in a space craft, or the software behind an MRI machine?

Those are orders of magnitude easier to test.

Any time you are dealing with a system with that many users, you are going to introduce a lot of chaos (in its mathematical sense). Chaos is nearly impossible to test for because there are just too many permutations.

You are (probably) right that any particular piece of a trading system would be easier to build and test than the examples you gave, but in aggregate, I think it would be much more difficult.

Major issues just a week after moving to a new Linux-based system [1]? It has potential to be a fairly nasty PR-blow.

It's a new system that does a ridiculously difficult thing on a scale that makes it nearly impossible to test completely.

London Stock Exchange is live, offers no real explanation for outage

I suspect malicious activity or automated trading systems could be the source of problems, in addition to engineering. Don't assume it's automatically Linux vs .NET.

London Stock Exchange has called a crisis meeting with market data vendors

The last paragraph is quite interesting - 3 different exchange platforms having problems in the same week one after another. While this might be just a coincidence... maybe someone knows how to crash the systems?
