I'm surprised I haven't seen more posts yet about this. A rogue or compromised admin put JavaScript redirects on Lemmy.world as well as changed the name and some other things. The other admins removed the compromised admin, but then about 30 minutes later they were reinstated and started wreaking havoc again. The instance eventually went offline completely.

Thanks for the explanation. What terrible news...
Seems we're still in the early stages for this major happening, so I'm sure there will be more information released very shortly.
I guess this goes to show why a federated networks are important, and why people shouldn't flock to the most popular instance. Right now many communities are down because of this, while the ones that were wise enough to set up their own instances are unaffected.

That's precisely why I joined vlemmy.net, but now that seems to be suffering some other issue and is just completely down since yesterday...
Growing pains, I suppose. Mastodon had a serious vulnerability discovered a few days ago too. Looks like the fediverse is gonna need some time to adjust to this sudden massive wave of users.
