The problems occurred at market open; we were aware of the issue when it happened, but the problem was not on our data servers, rather those of our data-vendor. We have been told that the issue came about due to the Stock Exchange issuing an update to its reference feed that hadn't been announced, which knocked over a number of systems. The issue affected a number of vendors, so the problems will not have been limited to the service lse.co.uk provides.
We're obviously looking into what occurred, and will be seeking re-assurances from our vendor; but when it appears the problems originated at the source of the data (the Stock Ex), there's very little we can do in these scenarios. Having 5 backup feeds wouldn't have made any difference in this case sadly.

The sort of problem that occurred today is highly frustrating for us, as it's simply outside of our control.
