The Brazil zone’s been historically underserved, and there was a drive a while back to add more servers.
In recent days the active server count has sometimes dropped as low as 8 IPv4 servers and 4 IPv6 servers (though it’s doing a bit better at the moment).
China’s justifiably the focus right now, but as one of the remaining (IPv6) server operators, I would appreciate it if some people signed up for Brazil again too.
I have one (foreign) VPS in the Brazil zone. The IPv4 spikes were too much for me and I removed my IP (somewhat accidentally) a long time ago. The IPv6 traffic is normally fine, but when it drops to 4 active servers and I get 25% of the entire country, I get like 6 Mbps of inbound traffic. If this keeps up I’ll kind of have to drop out.
