Those data rates that ckenisell posted above look really good to me -- especially the upload rate. I'd love to use Crashplan to back up more of my stuff and 70mbps up would make that practical.
Regarding AT&T Gigapower, my understanding is that at the $70/month level, they monitor your HTTP traffic (not HTTPS) for targeted advertisement and may replace ads on web pages. To avoid this "feature", it's $99/month for 300MBPS. See http://www.dslreports.com/shownews/ATT-Offers-70-1-Gbps-in-Austin-With-a-Big-Catch-126969
I have not been able to find out if AT&T has bandwidth caps, or if their TOS allows non-commercial home servers. Google Fiber's TOS does allow such servers; I assume they have no caps but I'm not 100% sure.
Anyone know about AT&T's policy on home servers and data caps? At one point, uverse was going to impose caps (something like 300GB) but they might have backed off on that.
Regarding Google fiber installation: someone posted a bunch of permits Google filed with the city for utility work south of the river. So it's real. I understand they'll be using Austin Energy's power poles and underground pipes. My neighborhood has all underground utilities and, after putting in a pool, the electrician said I needed more power to the house -- Austin Energy sent a giant truck and was able to replace the underground cable (oddly enough, aluminum, as big around as my forearm) from the transformer to my meter in about 20 minutes for no charge. So if Google (or AT&T) can use the same underground plumbing, I can see it being relatively inexpensive.
We do have a relatively new uverse installation at the end of our block, but we aren't on the list for the initial Gigapower rollout. But the pricing/monitoring means I'll likely wait for Google. They also have a terrific DVR, from what I hear -- records 8 programs at once.
TWC is now advertising a 100MB service but I have no idea about the pricing or if it's symmetrical (same up as down). Anyone know?
