We've had FTTP since last August where I live in Worcester. Ours so far (hope I've not jinxed it now) has been working fine.
But other parts of the estates (by sons, so luckily he's not changed to it yet ) and lots of other areas in Worcester have lost FTTP connections totally for the past 3 days and still ongoing . Apparently City Fibre , installing it on behalf of lots of providers , have hit problems doing emergency repair work & have f**cked it all up , and taking longer than expected to get everyone back.
We've still got the old box inside to hopefully connect the modem to use the good old fashioned connection if it happens to us (City Fibre installer advised to keep it to revert back if needed) .
