"The reason Cogent has a bad name in the hosting industry is because lots of two-bit hosting shops sprang up on Cogent bandwidth, and the hosting shops oversold their bandwidth. This is not Cogent's fault."
Hmmm.... sounds like GFY is good for spreading FUD
Doesn't matter if your provider uses Level 3 or Cogent, if they oversell their offerings, they will be slow - period. Why colo-cation is top notch is they don't oversell their bandwidth.
