Ive had intermittent very slow browsing. Done speed tests (which are fine) and tracert (nothing too out of the ordinary compared with the ones posted on here) and im not really any the wiser. I will probably leave as I know they are a good ISP gone bad but just wanted to know what the problem might be. Was half thinking it may be DNS issues?
I've had the same problem of intermittent slow browsing too, with no obvious problem. Not convinced it's DNS either.
It might have happened with the switch over to cogentco but may be just coincidence.
