To help limit spam, the hub will now prevent a single IP from advertising multiple servers unless otherwise whitelisted. Any multi-server networks already on Multiverse have been domain and IP whitelisted, so no existing servers should be affected by this limit.
For future servers not yet on Multiverse: if you only have one server, you are not affected. If you have more than one server being advertised by a single IP, please contact Skye with either your (more ideally) domain name or (less ideally) IP of server sending advertising pings along with expected number of servers.
