Did you receive an email with your login info?

there is also https://whatsmyuse.net/ that is not in a confusing map form. also i dont think that map is current as can be.

it shows in the provider section. do you mean in the backbone section? it is just under the Omicron(AMS) backbone, nothing really special about it

yes this seems grossly out of date. https://whatsmyuse.net/ is better laid out imo and seems to be updated as far as the backbones that are gone or resellers that have moved.

Are you finding the posts to begin with on Geek? How old are the posts that are failing? if they are under 3000 days then they are most likely taken down and it really wont matter which service you use. Copyright requests hit them all. You either need to find a repost on geek or on another indexer or move on. Some stuff is just targeted much more than others. If they are really old posts then you may need an account with higher retention (still no guarantees its there though). that is where the frugal blocknews account with yearly comes into play.

Frugal imo is best bang for your buck and you get usenetfarm to go with it.
