Nothing official I'm afraid. Atos run the mainframe that TRUST and many other applications run under, and although making enquiries to TRUST appears to be working, train statuses are not being updated, and no train activation messages (a task runs every 30 seconds and this appears not be running) are being sent out.
As with all outages like this, I imagine the underlying cause will be pretty straightforward, the process to determine what's wrong pretty difficult, and the resolution hopefully soon.
