So I noticed a couple days ago that Bitcoinica suddenly went down. I thought perhaps someone else would start a thread, but after a few days with no posts I decided to look into it more. Well, as you probably guessed from the subject, Bitcoinica is not down, but it appears Comcast's DNS servers are no longer resolving the host name. Digging a little deeper, I found the following:

First, here are the current DNS addresses for Comcast users (I think it's for all users):
http://dns.comcast.net/dns-ip-addresses.php
75.75.75.75
75.75.76.76

I thought those IPs looked rather odd, but apparently they're legit -- and easy to remember. But do they do anything different? Well, here's a quote from the above page:
Quote
These IP addresses are distributed across many servers via Anycast for redundancy and reliability. As part of our ongoing efforts to protect our customers and provide great security features, DNSSEC validation is now automatically included as part of Comcast Constant Guard™ from Xfinity. Learn more about DNSSEC at our DNSSEC Information Center or by watching this short video.

Click on DNSSEC and you get the following page: http://www.dnssec.comcast.net/

DNSSEC Deployment Completed!
Tuesday, January 10, 2012

As noted here on our blog, we have signed all of our domain names and all customers are now using DNSSEC-validating resolvers. Comcast is the first large ISP in the North America to have fully implemented DNSSEC, as part of ongoing efforts to protect our customers with Constant Guard™ from Xfinity.

So my bet is that somehow their DNSSEC initiative has decided that bitcoinica.com is not a safe website or something. Any thoughts on this? Other than changing my DNS server, it seems I can at least just connect directly to the Bitcoinica IP address (50.56.4.62), but https is not available if I do that, and come to think of it https://www.bitcoinica.com gave me the crossed out https as well. Perhaps that is the problem: Bitcoinica's certificate isn't valid, at least with Comcast? Does that sound right? Anyone else have thoughts or other details on this?

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.
Advertised sites are not endorsed by the Bitcoin Forum. They may be unsafe, untrustworthy, or illegal in your jurisdiction.

Wow and this before SOPA even. It is my understanding that this is what SOPA would be like.

For the time being use googles DNS servers 4.4.4.4 or 8.8.8.8

That is the sites logo so that is the site itself that is blocking you out. It is a bitcoin casino.

so why would the casino ban me on their end due to "local laws in your area"?  you think that they're that paranoid to do this?

you are wrong is about about legitimate business, remember law is a tool for that state to make delinquents, then put said delinquents on jail, then use the jailed man to scare old ladies and increases taxes, a legitimate business only need to be fair with its users no to make surf on a ocean of stupid regulations

tl;dr get some reality check

+1 although this is more of a "reality of the future, right now" that relatively few still have yet to comprehend.

Are you serious?
How long do you think you would manage without those authorities?
Taxes pay for police, infrastructure,fire department, garbage disposal and other services.
Without those authorities you would get robbed twice a week and shot once a month and live in a dumpster.
If you don't want any authorities? you are welcome to move to 3rd world country - no taxes there, they will simply take all of your money and shoot you.
Look at bitcoin - no authorities - have you seen how many scams are out there? Sure you will say you get scammed - its your own problem. but i am sure you will change you tune if you will be the one who is scammed. ("it will never happen to me, i am supersmart and can't be scamed" - yeah, right)
Law is a tool to keep a community alive and functional. This tool is sometimes misused. but calling law " tool for that state to make delinquents" just shows that you have no idea how it works and what it actually does.
you are the one who needs a reality check

Less law / authority in a virtual world makes sense because any threats are not physical ones.

But in a not-so-distant transhumanism future, where carbon based life merges with the technology it created, we may think twice about litigation in virtual space as well.

they are not directly physical - but they can cause physical threat
If a hacker takes all of your money out of your bank account and charges your credit card
since banks are regulated they will be held liable for the hack and reverse those transactions
on the other hand if you had all your money in bitcoins and got hacked - you are screwed - you wont be able to pay any bills , buy food etc. this is a physical threat although it is caused by a virtual transaction

Have you been to a third world country? Do you really think there are no authorities there and everyone really gets robbed twice a week and shot all the time? I sincerely hope you were using hyperbole.

many countries in the middle east like qatar or kuwait , no taxes to pay, all the services you mentioned above are paid by oil (natural resources of the country)
There are still laws, people dont steal from each other or they will get jailed
And actually in this case there are still taxes but they are not direct
Instead of the citizens of that country using the oil for their profit and paying some of it as taxes - they give some of the oil itself to the country instead - meaning the tax isn't paid in currency but in oil. So there are taxes unless you claim that the oil belongs to the authorities in the first place - and not to the citizens of the country - which IMHO is wrong.

tl;dr
they are paying taxes with resources since the oil should belong to the citizens and not only to the country/autorities

......
the main question is did i sign any contract for this services ? last time i did check i dint have a second choice, last time i did check calif had some city with private police that is and was way more effective that state police and that did offer police service under private contract

all this because this services got provided before calif even was part of USA, again why i need the state to steal my income ?
1) nobody forces you to live in the USA. if you stay in the USA of your own free will - you are signing a contract with the state. dont like it? move
2) So you prefer paying to a mafia rather than to official authorities? fine - its your choice. you still pay...

To red:
i was using it as an example hoping nobody here knows what i am talking about
though there are some 3rd world countries where the government has no real power or in a constant war with its citizens - i wouldnt call that proper authorities, and people do get shot and robbed quite a lot there - unless you pay the local gang

Is that why you don't steal?

Have you noticed that people are still stealing even with the laws?

How about we pay if they actually deliver? That's a pretty damn low bar btw. If I deliver you an unrequested service it doesn't matter how awesome it is, you don't owe.

1) nobody forces you to live in the USA. if you stay in the USA of your own free will - you are signing a contract with the state. dont like it? move
why should anyone move ? when you dont like your job you look for another job or you go on another country ?
when you dont like your job you look for another job
when you dont like your country's laws you either find another country or make sure the laws are changed (which is improbable in the USA)

2) correct. but the regular mafia isnt democratic. so in my opinion they are much worse. if you dont thinks so you are welcome to join/pay them instead. if you dont want to pay at all you will have to conquer your own territory and start your own country. good luck with that
