Hi there I’m new here also
I have just read a few comments on here so I thought I would like to let you know of a few things I have come across last December.
I have put a few friends of mine on Newsgroups and have had a few tell me there speeds have gone terrible too, 2 are on Newshosting and 1 on Giganews ... they are all on Virgin for their ISP the Newshosting problem was solved when I told them to change their port to 3128 but the Giganews problem was not solved until he signed up to the SSL package (which is what I am on at the moment and Virgin ISP).
So that in my eyes, is surely Virgin throttling Newsgroups, I don’t know why SSL is working as I have been on that for years and never have been throttled (not including the 5mb rubbish)
