Somewhere along the line when I wasn't paying attention, Comcast High-Speed Internet revealed that they outsource their usenet
feed (netnews.comcast.net) to Giganews, a respected and reliable usenet feed provider. For Comcast subscribers, there is a 2GB/month download limit.
I did not know that.
Last month I downloaded 2GB of insert_random_binaries_here from netnews.comcast.net. Apparently, when you hit the 2GB limit, you are banned from the service for an undocumented period of time. Nice, thanks for the warning.
Maybe time to try an alternate service. http://www.usenet-provider.com/ has reviews of many public (fee-based) usenet newsfeed providers.
I wish Giganews had pricing options like AstraWeb or Teranews. Daily limits make a lot more sense than monthly limits.
