Trying to setup My BT Cloud, I clicked the My BT Cloud link on MyBT.
I expected to get desktop software of the sort that I use with the sky full of clouds I use. Instead I got a broken link :
The server encountered an unexpected condition which prevented it from fulfilling the request.
Fortunately, it seems that I am not the first person to have had trouble with BTCloud software so I managed to find a link for the software.
I assume that this is a general problem and not just something that has clobbered me. I tried three different browsers and got the same result.
