Its the Southwater exchange.
Southwater Exhange on SamKnows
Ok that really odd. I checked the exchange on SamKnows earlier and it said:
BT Wholesale information
ADSL status: Enabled as of 31/05/2002
ADSL Max status: Enabled as of 31/03/2006
SDSL status: Not available
21CN WBC status: Not available
FTTC status: Available in some areas
And I just checked again and it now says:
BT Wholesale information
ADSL status: Enabled as of 31/05/2002
ADSL Max status: Enabled as of 31/03/2006
SDSL status: Not available
21CN WBC status: Enabled as of 01/01/1970
FTTC status: Not available
Note that FTTC now says "No Available" and 21CN says it was enabled in 1970! (I think thats a 0 timet value for any programmers out there, or unix epoch for unix fans).
I still have both browser windows open, so I can see that it has changed in the past hour or so!
