I am currently planning on starting a new hub server. I have 2 of the servers already, but would anyone recommend a cheap service that would be great for the bungee proxy and the lobby? Maybe it could be used for others servers.
If you're getting into the multi server bungie setup and have any technical ability whatsoever, you may consider getting into dedicated hosting options. A bit of time and effort and you can learn enough linux to get up and running with something like linuxgsm
Shockbyte is "Okay" the issue really isn't the host as much as it's the specs. There are free hosts for that matter that allow for a small SMP that are REALLY good and full featured... So it REALLY depends on what your looking to do. If you say I need 100 + players on a heavily modded system I would say any cheap "package / build" is gonna let you down. The owner of Buildcraft (a whitelist SMP) was using one of the mentioned services but eventually as the world grew and more were playing the server just couldn't keep up. He moved to Cubedhost changed the amount of RAM and there has been NO issues since.
