I believe he said he's paying for 1.5 Gbps capacity over a 10 Gbps uplink (though it's currently only set at 1 Gbps and needs to be fixed). So the maximum shared bandwidth is 1.5 Gbps, but he has physical headroom if he needs more.
I won't disclose what the usage is but with everyone live there is tons of headroom. The redundant carrier and construction is underway as well.
I can use other strands or run them in the second conduit we installed.
