I live in London and my speed is 64-69Mb, only two choices of BT/Openreach or Virgin Media where I live sadly. I have thought about switching to VM as they seem more stable where I live now, I do check other fibre options like Community Fibre, Hyperoptics and YouFibre regularly to see 8f in my area, sadly not yet :o(

One bug that irks me is deleting an email on a folder with sorting such as grouped sorting and Thunderbird loses the sorting settings, then I have to reapply the sorting settings again…gah
