Install a NeoForge 21.10.63 (MC 1.21.10 ) server through the Control Panel (Servers → Select your server → Game servers → Add Game Server → NeoForge 21.10.63 (MC 1.21.10 ))
Had total 30 minute downtime in a month of service which was resolved, communicated well and an extra 3 days of service was added for free. Great service, highly recommend
