Handy for those wanting to know a bit more information without having to scan the debugging tool 
Me, looks over shoulder
Well I have used an application that I wrote a little while back, so I don't need to view via the debug tool, which in my case is cool due to less bandwidth that I am using up on my already slow connection, but if they start to add new features and fix the bugs etc I will probably end up using their page.
They just need to sort out the cookies and token issue that results in a continuous loop of the cogs/blue spinning rings, this is due to the page not handling the badreferer error.
This issue happens when checking either different address or phone numbers with a few minutes gap between lookups.
Like I have already said, I think speeds will be the next nice addition, due to that information has recently appeared.
But its looking good so far.
One last thing if BT Openreach is reading this...
Please remove the cabinet reference from the stage part, like for example.
Cabinet status: Please check the cabinet fibre journey above
It would make more sense it saying.
Fibre status: Please check the fibre journey above
Granted it makes sense if everyone is put on FTTC, but it makes no sense when it keeps referencing a cabinet if its FTTP.
They are already doing parts of it for the following:
[FTTC]
Great news, you can order a fibre service. Please get in touch with your service provider.
[FTTP]
Great news, you can get Superfast fibre directly to your home. Please get in touch with your service provider for more details.
Also "Cabinet Fibre Journey" should be worded just "Fibre Journey" it suits both FTTC and FTTP.
