This map will help you determine which provider you choose for your service. The top tier resells their groups to the providers below on the tree. For best results subscribe to one of the providers in one color; and buy block access from another provider. This will help ensure that the posts that you need to download are complete. It also shows the retention time of each provider; however I have found this to be inaccurate; many of the providers host messages for a much longer timel
Important Note: There is an update to the provider map; this is 2022 if someone knows the changes and can edit the .svg file or provide the information it would be greatly appreciated.
yes this seems grossly out of date.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.
