it's the world wide web buddy, anything can happen.
when i got my smartbro installed last May, i already knew they have 2 options for checking speed which are 2Wire and TestMy so incase the result of the first is not satisfactory there's a second one to serve.
don't worry about posting your comments about smartbro. they will either collect it to improve their service or totally ignore it. after all, what they care about is the income.
