I noticed that the 24 Month 900Mbps package went missing a few weeks back but surely its intended now with the 500Mbps package also gone:
All packages are still there for 12 months, going to assume this is the beginning of phasing out new customer to BT for broadband.
Both showing for me, or at least for an address that has FTTP!
Maybe try another browser?
How weird, youre right!
