21CN

[#1]

According to samknows.com I'm due to switch to 21CN by the end of November but the plusnet exchange checker has no date. Just want to see which is correct.
It's the Goole exchange 
Thanks.

The current BT Wholesale spreadsheet (line 1600) says November - https://www.btwholesale.com/pages/downloads/Community/Broadband_Community/WBC_SFBB_Dataset.xls

I Popped your number into the BT Availability Checker and it also came up with 30th November for the upgrade date.
