Not just the public sector that has IT problems…

Great. The day the US mortgage bail-out sends world stock markets shooting up, and this happens:

The London Stock Exchange has suspended trading due to a technical problem that has affected its trading system.
A spokesperson said "connectivity issues" meant traders could not connect with the LSE trading platform.
The problems mean that no share orders have gone through, the LSE said, but it is working to restore the system fully as quickly as possible.
A well-spoken electronic woman added: "Your trade has been placed in a queue. Please hold. Your business is important to us."

(That last bit is a paraphrase.)
