I'm on the contention ratios of 20:1 with a 2Mb Lite package. In April when MAxDSL is activated on my account I have the option to keep 20:1 for £5 month extra or be automatically changed to 50:1. The question is will it make much difference? Am I likely to see a slowup in my service at 50:1 compared to 20:1? Any advice on this subject will be most welcome.
