[TriLUG] OT: Google datacenter in NC

Oh, don't get me wrong.  You're right that TWC has lots of capacity in the
area, fiber-wise.  It's the cable modem termination systems (CMTSes) that
are the bottleneck.  Basically, they can only handle n subscribers per
downstream, and those get divvied up per upstream.  They have to manage
those pretty tightly, lest they oversubscribe a card on a CMTS.  When one
does get oversubscribed, they have to do a node split to redistribute. This
means that they have to have additional capacity on another card to which
they can move customers.  That means downtime in order to complete the node
split, and especially since introducing the VoIP services cable companies
are very reluctant to do node splits.  At this point, if TWC were to offer
20x2M bandwidth, they would have to do so many node splits, put in to many
CMTSes (especially in concentrated areas like the Cary/Morrisville/Apex
drop) that they would have a significant net negative, with significantly
more capacity required to accommodate the subscriber growth that it would be
far too expensive to consider.  So the capacity is there in terms of fiber,
but the pipe isn't the only piece of infrastructure to consider.
