I don't see anything listed that indicates operation that is at all different 
from any other service provider network.

The "capacity" issue listed is not an issue at all. It's simply inciting anger 
and the same rhetoric that pollutes the legitimate discussion of backbone 
network constraints.

When you shout "conspiracy" without offering verifiable facts, and not 
accounting for the cost (and time) it takes to upgrade networks (much less the 
fact that it requires capacity upgrades on both sides, in this case between 
TATA and Comcast), it makes the whole argument invalid in my opinion.

That and the "backdoor santa" thing makes me believe the whole thread is 
designed to flame rather than promote the discourse that is the hallmark of 
NANOG. I really hope that there are moderators about to verify this: With these 
kinds of people about I'm less likely to post anything of substance.

Sincerely,

Brian

Actually, there are plenty of access providers with 2:1 ratio (more ul
than dl). It's not a matter if you're access provider or not, it's a
matter if you offer decent upstream speed or not.

In my experience, someone with 10/10 megabit/s ETTH compared to someone
with 24/1 ADSL will download the same amount of data on average, but the
10/10 will have four (4) times more upload usage, bringing the ratio from
2:1 (Dl:Ul) on ADSL to 1:2 (Dl:Ul) on ETTH.

So because Comcast is offering low upload speeds, they'll have low
outgoing amount of traffic compared to incoming. With more and more ISPs
offering more symmetric dl/ul speeds, we'll approach 1:1 ratio more and
more...
