I don't see anything listed that indicates operation that is at all differe=
nt from any other service provider network.
The "capacity" issue listed is not an issue at all. It's simply inciting an=
ger and the same rhetoric that pollutes the legitimate discussion of backbo=
ne network constraints.
When you shout "conspiracy" without offering verifiable facts, and not acco=
unting 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 de=
signed to flame rather than promote the discourse that is the hallmark of N=
ANOG. I really hope that there are moderators about to verify this: With th=
ese 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...
