"I couldn't run the small datacenter in my house with it though.".  -- Are you 
using Cox to do this?

I home office and twitched from a consumer package to a business package so I 
would have the ability to run a server.  I ran a server part time for testing 
only.  I was testing out the Qmail Toaster.  

I had a bad experience running a server about 10 years ago.  I left the email 
relay open and was exploited.  Since then I have been leery of running server 
out of my house. 

My cable connection has been very stable with just a couple of outages.  I 
think those outages where on my consumer connection.  I do not think I have had 
any outages since twitching.

I'd be interested to hear if you are using Cox for your home based data 
center.

Qwest/CL DSL has always proven spotty *at times* with anyone I've ever known 
using it.  As a network guy I inquire with fellow geeks I know, and they let me 
know.  Generally the residential side of Qwest/CL fairly weak on 
troubleshooting most issues because of simple physical problems that often 
cannot easily be overcome with 2wire systems.  If you can get VDSL, it's decent 
from what I've heard, as long as you have new wiring, in a new area, and live 
close to where every they dropped the local dslam.  Most fall NOT into this 
category.

Data comes in the form of modulation, and consider 10baset requires 4 wires 
still, gig ethernet 8.  2-wire is poop compared to the modulation and speed 
capable on _shielded_ coax.  Qwest has simply had to push the envelope with dsl 
tech to remain relevant in the market, eventually resorting to new wiring 
(twisted-pair i think), often with some shielding now to achieve it which is 
hardly traditional for a telco outside of business service.  Eventually they 
had to begin to roll fiber as they were reaching unpractical limitations in 
their 2wire tech to modulate data at *competitive speeds*.

Fixed point-to-multipoint ala old sprint broadband and various others operate 
in parts that do it too now, sometimes a decent alternative where available 
I've heard (cave creek area).  At least until it is oversubscribed to hell.  
Sprint acquired independents here in town setting them up, but ultimately they

Not sure this isn't the eventual outcome of any wireless deployment.

Satellite is a last-resort option with as stated, latency and bandwidth caps 
(extreme point-to-multipoint far, far away).

If celco's weren't so greedy/proud of wireless LTE tech, it would be decent as 
a fixed solution as well as mobile as latency and throughput is much improved.  
I couldn't run the small datacenter in my house with it though.  I can however 
get a LTE EHWIC for a Cisco router now that customers can and do use as a 
"backup" solution when someone back-hoe's your businesses fiber.

Qwest/CL fiber deployment, like fios is "pon", passive-optical network based.  
These are not to be confused with anything like optical ethernet, sonet, dwdm, 
etc that are "active" optics.  Cable, dsl, most non-optical (generally) are 
subject to async behavior as you have a small modem, and a very large cmts and 
active amplifier network driving very large coax feeds at headends and active 
optical from there.  Fiber doesn't have so much those physical limitations so 
long as the laser can use power in the diode to shoot your frames from here to 
there some ways (active zx single-mode optics can shoot 60km for gige, raman 
based dwdm amps much further).  PON is a cost-effective way of aggregating 
fiber in a controlled fashion as you somewhat would a copper plant, only now 
the techs roll with portable fusion splicers and otdr's instead of qam test kit 
for coax.

Cable is where it's at, when fiber is not.  I've too worked at cox, and 
actually back to @home and offshoot isp back in the day when they started the 
tech before cox as media whores figured out what IP was. The modulation and 
timing that drives docsis 3.0 is very scalable for a copper means, and it's 
nothing cox will need to dig up and replace anytime soon.  Other than being a 
bit proud of watching and working it along the way, it's solid tech.

I have some issues with Cox ultimately, but they are one of the less evil of 
the isp's out there, and generally have much improved stability over most 
anything else.  Generally speaking, the only time I call them is when truly 
something dies (arizona is hell on coax), as I don't require network support 
otherwise.  I've used them off and on a good 14 years for data, and as long as 
you have a clean physical connection (modem levels can tell you/them this), 
it's pretty damn solid.  Business services gets you someone out to fix your

I do, mostly my lab, but I have it running on a residential connection, 
and only the mid/20mb package.  I can ipsec or ssl-vpn to my asa, and do 
what I need to remotely when on business from my lte router from my 
internal network.


I don't use a lot of bandwidth (aside from personal usenet reaping), 
it's mostly internal stuff with vmware, various linux systems, ad 
controllers to play with, storage, and a host of other vm's, but it 
amounts to quite a few.  That mostly stays gige within my house though. 
 I nat everything out one address, and vpn in for everything else.


I'm planning to go business services once I actually need higher uptime 
than I get now (ie someone to come when it breaks asap), and they're 
good for it.


Pro-tip - If you have a relation with a cox account manager (or know 
someone at times) from bigger businesses with fiber connectivity or 
such, you can sometimes get a deal as a "teleworker" package personally, 
which amounts to "bulk" connectivity for business service cable to 
aggregate their workforce on cox connections with business-level mttr. 
Generally its the highest-service level package, business response, and 
~$80 dollar price tag at last check.


It's usually kind of a hook-up deal, but depends if your business 
account manager likes you spending money with them, and enough of it.  :)

Qwest/CL DSL has always proven spotty *at times* with anyone I've
ever known using it. As a network guy I inquire with fellow geeks I
know, and they let me know. Generally the residential side of
Qwest/CL fairly weak on troubleshooting most issues because of
simple physical problems that often cannot easily be overcome with
2wire systems. If you can get VDSL, it's decent from what I've
heard, as long as you have new wiring, in a new area, and live close
to where every they dropped the local dslam. Most fall NOT into this
category.

Data comes in the form of modulation, and consider 10baset requires
4 wires still, gig ethernet 8. 2-wire is poop compared to the
modulation and speed capable on _shielded_ coax. Qwest has simply
had to push the envelope with dsl tech to remain relevant in the
market, eventually resorting to new wiring (twisted-pair i think),
often with some shielding now to achieve it which is hardly
traditional for a telco outside of business service. Eventually they
had to begin to roll fiber as they were reaching unpractical
limitations in their 2wire tech to modulate data at *competitive
speeds*.

Fixed point-to-multipoint ala old sprint broadband and various
others operate in parts that do it too now, sometimes a decent
alternative where available I've heard (cave creek area). At least
until it is oversubscribed to hell. Sprint acquired independents
here in town setting them up, but ultimately they oversold it to
death, and finally shot it in the head to finish years later. Not
sure this isn't the eventual outcome of any wireless deployment.

Satellite is a last-resort option with as stated, latency and
bandwidth caps (extreme point-to-multipoint far, far away).

If celco's weren't so greedy/proud of wireless LTE tech, it would be
decent as a fixed solution as well as mobile as latency and
throughput is much improved. I couldn't run the small datacenter in
