nearly every instance other than Lemmy.world is having federation issues with lemmy.world right now.

What do you mean? Having a quick test right now

It does not seem like “nearly every instance is having federating issues with LW right now”.

that defederates from at the very least Hexbear.

It’s always the same issues, there is no generalist instance that fits the bill:

• https://lemmy.ca/instances is Canadian-focused, so non-Canadians aren’t probably going to use it because they would think they “don’t belong”
• https://feddit.org/instances block HB and LG, but is German-focused
• https://lemmy.blahaj.zone/instances, but is queer-focused

You might have higher chances of convincing lemm.ee, lemmy.zip, lemmy.dbzer0.com, discuss.tchcs.de to defederate hexbear, than getting a small instance that does popular enough to enter the top 20

Or you can convince lemmy.cafe to get another admin, and get a bit more “professional” (a la lemmy.zip)
