Both were down for me before, they seem to be up right now but just made this account on Lemmy.blahaj.zone (Henry is the name of my actual blahaj lol). It’s probably because of the traffic influx from reddit refugees from the absolutely disastrous spez ama (where he doubles down on everything and doesn’t apologize at all). Allegedly they’re trying to suppress Lemmy mentions but I guess it’s not working well enough lol
A good problem to have although long term we’re going to have to figure out how to deal with these spikes in traffic.
As long as you get a public IP address, a domain name and TLS certificate, you can federate with other servers.
I run mine in a small Hetzner box. Two gigabytes of RAM, two AMD cores, it’s almost like doing nothing even I’m federating a ton of messages all the time regarding the logs.
