21CN down on Inverness Macdhui exchange?

Sorry if this isn't the correct place to post this, its a bit of a longshot anyway.

My adsl (of the type 21CN/WBC/whatever you want to call it!) has been down almost a couple of hours now and when I say down, my router has totally lost all connection with the exchange and the light is out. I have my iphone tethered with my pc at the moment to get online.

Does anyone else have the same problem, or perhaps know of where I can find out any information at this time of the night, I tried BT 150 and then some other number I got off them but to be honest i'd be as well asking my cat.

Many thanks,

Contact your ISP.
Which ISP is it?

I'm with AAISP - its back on now, just frustrating when it goes off late at night and you can't get in contact with anyone.
