My install was completed finally on Tuesday, and since then I have had a letter from TalkTalk saying that there had been upgraded in my area and that ~900Mb/s was available. That was odd, as before the install when I checked the (BT/Openreach) line checker said ~60Mb/s was maximum available.
When contractors took up a few blocks of my drive, they showed me the Virgin trunking (which I didn't know existed) and the Openreach trunking. The fibre is blown through the Openreach trunking on my install.
So is Virgin leasing capacity from Openreach on my install, or is it indeed Virgin? I ask as I am trying to make good the old installs twisted pair cable (find a suitable IP67 box - something like the SCP to hide the mess). But if this is Openreach, theoretically I would never need this cabling again (so I could just seal all my holes up).
Hope that makes sense.
