I have just run the ADSL Checker (first time for some months) and that seems to have changed format, viz :-
Telephone Number *************** on Exchange KIMBOLTON is served by Cabinet 2
|WBC ADSL 2+||Up to 2||--||1 to 3.5||Available|
|ADSL Max||Up to 1.5||--||1 to 2.5||Available|
|WBC Fixed Rate||0.5||--||--||Available|
For all ADSL and WBC Fibre to the Cabinet (FTTC) services, the stable line rate will be determined during the first 10 days of service usage. Throughput/download speeds will be less than line rates and can be affected by a number of factors within and external to BT's network, Communication Providers' networks and within customer premises.
The Stop Sale date for Datastream is from 30-Jun-2012; the Formal Retirement date for Datastream is from 31-Mar-2014. The Stop Sale date for IPstream is from 31-Oct-2013; the Formal Retirement date for IPstream is from 31-Mar-2014.
If the End User wishes to migrate from their current Broadband supplier they will need to contact them in the first instance to obtain a MAC (Migrations Authorisation) Code, and then contact their new Broadband supplier to arrange for the service to be migrated.
Note: Please note that postcode and address check results are indicative only. Most accurate results can be obtained from a telephone number check.
Thank you for your interest.
Was it some sort of update by BT Wholesale like the speedtester ?
