this is dependent on location vs BT's nodes.
BT have no node near me so my pings on BT wholesale arent optimal. On easynet I used to get 9ms to london, BT wholesale its over 15ms, and on 20CN it was over 20ms.
On BT retail I know strange routing occurs as well eg. people in london or near to london see their traffic to london endpoints going via sheffield. However I dont know if plusnet has this weird routing as well, that may be limited to BT retail.
The bt wholesale network itself getting overloaded according to aaisp blogs is now uncommon and its not in BT's interest for that to happen as that then potentialy reduces throughput from isp's which reduces demand on backhaul which earns BT revenue.
I can tell you on infinity I see no signs of congestion at all 24/7 and that uses BT wholesale. Scouring sky's forums has more complaints regading congestion than BTr forums do.
