My school uses the core service havn't seen any problems with it as long as residential users wouldn't have to have the internet filters enabled, it blocks so many legit websites.
Anyone know and good sites I can use to do some reverse ping tests? I can't access command promt in school. Where you want pinging? jolt.co.uk? I'll try do them tomorrow.
Would be better if the service had the backhaul from JANET rather than Core/Azzuri has atleast some of their backhaul is from KC - I remember this from when the school I went to was on "Progrid" and the access went through a shared system with a few others schools... it was a KC IP. 212.50.183.x IIRC

JANET also has a much faster backbone.
