Service availability

We have set our website service standard at 99% availability.

Whilst we intend that this service should be available 24 hours a day, seven days a week, it is possible that on occasion it may be unavailable for very short time periods to permit maintenance or other development activity to take place.

If for any reason we have to interrupt the service for longer periods than we would normally expect, we will endeavour to publish in advance details of such activity on the home page.

Actual performance data for previous months is available:
