It will be interesting to watch how Altice handles both Suddenlink and Optimum. This is doubly true if they handle them differently. I'm on Altice/Optimum. They are directly competing with Verizon FiOS for much of their territory out east. I pay $80 for 200/35. There is no cap. Heavy users get "traffic shaped". By that I mean that the week when I uploaded a 100GB photo archive up to a web service, speeds started at my upload of 35Mb/s but settled down to 10Mb/s after a couple of minutes. IIRC I could still add upload streams at that time and they would run at whatever bandwidth I had left. But big stream got limited to 10Mb/s after a few minutes of running full speed.
Someone on the Optimum Online Forum at dslreports should start lurking in the Suddenlink forums and vice versa.
