[kwlug-disc] Cable internet providers

[unsolicited]

IIRC, much like DHCP static IP request - anyone using this IP, yes, try 
another, keep going 'til you get enough channels.

It is all Rogers from home to their building, so they know what channels 
are in use. And it's all their equipment. (Which is why only Roger's 
approved modems can be used, by any supplier - their equipment has to 
grant access. i.e. Understand the schema in use / approve the MAC 
addresses for connection.)

Only difference beyond that is whether Rogers connects your endpoint to 
their internet PoP, or a 3rd party's on Rogers (Grand Cresr) premises.

Think if you were on Front St whether you back end connect to ... names 
are escaping me - Bell, Sprint, AT&T?, Rogers, Canarie, Uni<something>. 
Throw cable one way or another depending on which back end you 
contracted with. And likely more than one for redundancy. (Let alone, 
don't all their feeds come from Chicago?)

IIRC (year or two back), Acanac was starved to be able to add more 
subscribers in this area because the reseller side of the Grand Crest 
Place / Kitchener facility was maxed out. And it was Rogers that had to 
build out more capacity from Grand Crest to the next hop out. I -think- 
at the same time to other provider endpoints in the area too, but that 
doesn't really matter, here.

(So, there was no capacity issue between here and Grand Crest - i.e. no 
lack of Rogers channels / frequencies.)

Rogers eventually built out more capacity - Acanac was able to then 
accept more subscribers.

I didn't put this together with, later, noticing that there were now 
more cable internet offerings. e.g. vmedia. 'til a few weeks back.

[Seems to me this Roger's capacity / build out issues spanned a fair 
portion of Ontario, and was equally hitting Tek Savvy, Distributel, 
Acanac, each in their own respective geographic areas, at the time. 
Rogers had to hook up more fibre between their own distribution centres?]

Pity the resellers, whatever Rogers puts them through, Bell is also 
putting them through, but likely in their own unique ways. How they're 
not driven mad / retain their sanity, I don't know. Guess that's why we 
need the CRTC.
