We've got the highest package from them
Can't see any evidence of it so far.

But if they're using Ellacoyas to traffic shape I wouldn't be surprised.

PlusNet have been doing it for years.

virgin do packet shaping and throttling.
the only reason you dont notice it is because the higher your package, the more leeway they give you before they fuck you up.
