I just checked the date I noticed mine was put back on as "next 3 months", it was 5 months ago and still saying "next 3 months".
Although I did get feedback from the Project Manager via Openreach in November who said:
At the moment we are looking to start building the network from the start of 2021, however the build programme does run through to mid 2022 at the moment and we cannot say exactly where your premise sits in the build until we undertake access surveys – which begin early 2021.
