What a server actually uses.

The table below gives average bandwidth figures for the two server roles on the network.

Two-week average · July 2014 · NationCHAT traffic only

Considerations

Don't overcommit the uplink.

The averages above cover NationCHAT traffic only - they exclude the hosting site's normal business operations.

Rule of thumb

70% headroom, minimum.

Any site which consumes 70% or more of its available bandwidth for general business operations will not be well suited to running a NationCHAT server. This factor should be borne in mind when determining whether a site has resources to host a server.

Leaf burst

Size the link for the burst figure, not the average - quiet hours do not last.
