So there's lots of alternative instances that remain federated with Lemmy.world. It may take some number of minutes to move data between Lemmy.world and alternative instances, but you should be able to stay reasonably up-to-date to this support forum as long as federation works.

Ex: https://sh.itjust.works/c/support@lemmy.world

https://sh.itjust.works/c/lemmyworld@lemmy.world

The way "Federation" works means that lemmy.world and other hosts (ex: sh.itjust.works) will automatically retry and try to synchronize messages as https://lemmy.world goes up-and-down. Effectively, use the other-instances to "automatically F5 / Refresh" for you, so you don't have to manually F5 on lemmy.world.
