London Stock Exchange floored, again
Up and down like a ...
The London Stock Exchange is currently closed thanks to the failure of its trading platform.
Technically it's in a "halt phase" meaning orders can be cancelled but new orders cannot be made, nor can automatic trading happen.
At 8.03 this morning the market was paused as technical problems became clear, by 8.33am trading was halted.
A spokeswoman for LSE told us: "This is a market data issue with the LSE platform, separate to the bourse problems. We're working on fixing it now and will update the market before we restart trading."
The exchange, which has recently moved to a new Linux-based system called MilleniumIT, failed last Thursday.
And it failed to correctly close the market on Tuesday.
Oh, and there were some problems in January too ... ®
The OS is likely not the issue
I don't know why people think this is an open source vs closed source thing. The transaction software running the new system is closed source. I'd be very surprised if the OS had anything to do with the outage unless it was a broken driver or similar. More likely it's the application software running on top which has keeled over.
Have they tried the tried and trusted..
turning it off and on again?
Why are there so many uninformed posts on the register?
Not just here, but every day in almost every article. What kind of readership do we have these days?
I don't know anything about this problem, but from what I know of linux and software in general, it's most likely to be an issue with the custom trading system software that's been put in place. People use linux as a server because it's stable and highly customisable, and one less thing to worry about in a complex system. It's highly unlikely that it would be an OS issue to have brought about this issue, specially given the redundancy you have in place in distributed software systems.
Having sat in a data centre for 8 hours,ready to test, waiting for their operations team to figure out what they needed to do on the weekend before an exchange upgrade this comes as no surprise...
Except for the small fact that it is.
5 years without an unplanned downtime and counting.
