As already noted in the thread on our being defederated by lemmy.world, we are now refederated for the time-being. However, as noted by one of the l.w admins if there are any spamming issues we'll be back out again and if the upgrades stop we will have trouble with federation (lemmy.one is still not on the latest version, while we are), so there is still a need to sort this out.
The domain is fully paid up through to next year and there's no reason to suspect that the hosting will stop any time soon.
We've contacted the Admin through a few routes and we are hoping that gets his attention. We can then put into place other Admins and make sure everything is financial secure and doesn't just rely on one individual.
I tried contacting him here a while back. So far no luck. But I'm not gonna stalk him to get his own instance in order.. So I hope he pops up!
Yeah, we've given it out best shot, it's up to Tom now.
