What is going on with the water pressure in Mill Hill?

Does anyone know what is going on with the water in Mill Hill? Our house in Millway has had just a trickle coming out of the taps since early yesterday evening. We've had reports of friends near Mill Hill County High school having no water at all. A quick enquiry on the Affinity Water website reveals there is a burst water main Edgware. There is an alert detailing the progress of work indicting that there will be many households without water until this afternoon.

We would like to apologise for the inconvenience caused by a burst on a 21" inch main on the A41 in Edgware which may be affecting your supply.
Our technicians are on site and have been working through the night to repair the burst and to ensure your supply is restored as quickly as possible.
At this time it is unlikely that supplies will be restored until this afternoon
During this time, we ask you not to use any electrical appliances, that require a water supply, like washing machines or dishwashers and to conserve water from storage tanks during the time your water supply is interrupted
We would like to thank our customers for their patience whilst we carry out this repair
