>> 21CN WBC (Broadband) Not available
Because that information comes from the BTw database, which seems to have stopped supplying information. The dates are currently under review and unless BT has a firm set date, they are not supplying any information.
Theres many exchanges that were due to go live this summer that have been put back... and theres many many more exchanges that now dont have a date. Even the official 21CN BT site isnt giving out any information. :/
From this post
hereUnfortunately though WBC info is a bit sparce atm for some exchanges, as WBC and 21CN PSTN enablement dates are under review, therefore on many exchanges it will return "No info" but still show amber (due to a previous date being set).. and/or "Not available" for WBC
Not much I can do about that right now though since even the BT official switched-on site is stating "areas of the country are being reviewed between BT and other communications providers. This lookup tool is currently unavailable and will be updated as soon as possible"
Hopefully though as soon as the info is available again from BTw it should automatically start working again.
