Thanks @Edie@hexbear.net for letting me know about this!

The .org domain was apparently suspended, but the other ones are fine (.li, .se, .pm, .in). Their Wikipedia page should have an updated list of domains if this happens again.

The Reddit post from the archive team about this is linked, with the full text copied inside this spoiler.

Message from Anna: we’re fine

The .org domain apparently has been suspended. Our other domains work fine, and we’ve added some more. We recommend checking our Wikipedia page for the latest domains.

This unfortunately happens to shadow libraries on a regular basis. We don’t believe this has to do with our Spotify backup.

To keep our operations running properly we’re always looking for donations. We’re doing a fundraiser this month where you get double downloads for the entire duration of your membership.

Thanks for your continued support.
