Terrorism and internet blocking – is this the most ridiculous amendment ever? - EDRi
So, there you have it: Blocking is necessary, except it is not. Safeguards need to be implemented, except they don’t need to be. This approach is legal, except it isn’t. The text is based on the Child Exploitation Directive, except it isn’t. Is this really how we are going to create credible legislation on terrorism?

RFC 7754 - Technical Considerations for Internet Service Blocking and Filtering
The Internet is structured to be an open communications medium. This
openness is one of the key underpinnings of Internet innovation, but
it can also allow communications that may be viewed as undesirable by
certain parties. Thus, as the Internet has grown, so have mechanisms
to limit the extent and impact of abusive or objectionable
communications. Recently, there has been an increasing emphasis on
"blocking" and "filtering", the active prevention of such
communications. This document examines several technical approaches
to Internet blocking and filtering in terms of their alignment with
the overall Internet architecture. When it is possible to do so, the
approach to blocking and filtering that is most coherent with the
Internet architecture is to inform endpoints about potentially
undesirable services, so that the communicants can avoid engaging in
abusive or objectionable communications. We observe that certain
filtering and blocking approaches can cause unintended consequences
to third parties, and we discuss the limits of efficacy of various
approaches.

"Left-Right: A Concurrency Control Technique with Wait-Free Population Oblivious Reads" [pdf]
'In this paper, we describe a generic concurrency control technique with Blocking write operations and Wait-Free Population Oblivious read operations, which we named the Left-Right technique. It is of particular interest for real-time applications with dedicated Reader threads, due to its wait-free property that gives strong latency guarantees and, in addition, there is no need for automatic Garbage Collection.
The Left-Right pattern can be applied to any data structure, allowing concurrent access to it similarly to a Reader-Writer lock, but in a non-blocking manner for reads. We present several variations of the Left-Right technique, with different versioning mechanisms and state machines. In addition, we constructed an optimistic approach that can reduce synchronization for reads.'

Tor Bridge Relays
The next step in the Turkish twitter-block arms race.
Bridge relays (or "bridges" for short) are Tor relays that aren't listed in the main Tor directory. Since there is no complete public list of them, even if your ISP is filtering connections to all the known Tor relays, they probably won't be able to block all the bridges. If you suspect your access to the Tor network is being blocked, you may want to use the bridge feature of Tor. The addition of bridges to Tor is a step forward in the blocking resistance race. It is perfectly possible that even if your ISP filters the Internet, you do not require a bridge to use Tor. So you should try to use Tor without bridges first, since it might work.

Internet Censors Came For TorrentFreak & Now I’m Really Mad
TF are not happy about Sky blocking their blog.
There can be little doubt that little by little, piece by piece, big corporations and governments are taking chunks out of the free Internet. Today they pretend that the control is in the hands of the people, but along the way they are prepared to mislead and misdirect, even when their errors are pointed out to them. I’m calling on Sky, Symantec, McAfee and other ISPs about to employ filtering to categorize this site correctly as a news site or blog and to please start listening to people’s legitimate complaints about other innocent sites. It serves nobody’s interests to wrongfully block legitimate information.

Same Old Stories From Sean Sherlock
Sherlock’s record is spotty at best when it comes to engagement. Setting aside the 80,680 people who were ignored by the minister, he was hostile and counter productive to debate from the beginning, going so far as to threaten to pull out of a public debate because a campaigner against the ['Irish SOPA'] SI would be in attendance. His habit of blocking people online who publicly ask him tough yet legitimate questions has earned him the nickname “Sherblock”.

Blocking The Pirate Bay appears to have 'no lasting net impact' on illegal downloading
In the fight against the unauthorised sharing of copyright protected material, aka piracy, Dutch Internet Service
Providers have been summoned by courts to block their subscribers’ access to The Pirate Bay (TPB) and related
sites. This paper studies the effectiveness of this approach towards online copyright enforcement, using both a
consumer survey and a newly developed non-infringing technology for BitTorrent monitoring. While a small
group of respondents download less from illegal sources or claim to have stopped, and a small but significant
effect is found on the distribution of Dutch peers, no lasting net impact is found on the percentage of the Dutch
population downloading from illegal sources.

Hamlet is Banned in the British Library
Pretty hilarious account of the usual, run-of-the-mill overblocking in the British Library from last weekend:
I asked [the information desk] if they saw the problem, perhaps just the symbolism, of Hamlet being banned in the British Library. They shrugged. The IT department said there was nothing to be done, as it was only the British Library's wifi service that was blocking Hamlet, and the British Library's wifi service, they seemed sure, had nothing to do with the British Library. They were merely ships that passed in the night. Children crying to each other from either bank of an uncrossable river.

ISPAI Responds to Porn Filtering Debacle
Quite a strong statement:
The issue of access to age-inappropriate content is not a new matter and it is important not to have “knee-jerk” reactions which don’t solve the perceived problem and have major implications for the public’s right to access information in general. Notably the European Commission, as stated by vice-president Nellie Kroes [jm: sic], has come out strongly against blocking of the Internet, seeing it as an important platform for freedom of speech and she intends to “guarantee access without restriction.”  We in Ireland would do well to consider carefully the impact that any rash adoption or attempted copying of UK measures might have here in the light of current and future EU legislation and policy.

Irish Comms Minister Pat Rabbitte ignores calls for State role in blocking online porn
Good call.
Mr Rabbitte says that legal concerns attached to mandatory filters, as well as a fear of imposing censorship, have persuaded him against trying to force ISPs to impose mandatory pornography-blocking internet filters. "I remain to be convinced that blanket censorship or a default-on blocker is the correct or workable response," he said. "Even if it were possible to ensure that such measures were not easily circumvented or didn't inadvertently block perfectly acceptable content, the principled question of whether the State should be encouraging service providers to filter or block content to all users, regardless of whether there are children resident, would still arise."

Porn to be Blocked in the UK – “What’s new?” Say Pirate Bay Users | TorrentFreak
It seems likely that the ISPs will implement a system similar to the one currently being used by TalkTalk, as the prime minister will specifically single the ISP out for praise in his speech. TalkTalk’s HomeSafe is a system which filters out URLs based on a remote blocklist provided and maintained by…. well, no one quite knows. This is worrying since when things don’t go quite to plan there’s no one to complain to.

As previously reported, when TalkTalk customers are asked whether they want to block file-sharing sites, TorrentFreak.com is rendered inaccessible. Despite our pleas and complaints that we are a news resource, the company said it would not remove us from their blocklist. We doubt we’re the only ones being silenced.

UK ISPs Secretly Start Blocking Torrent Site Proxies | TorrentFreak
The next step of cat-and-mouse. Let's see what the pirate sites do next...
The blocking orders are intended to deter online piracy and were requested by the music industry group BPI on behalf of a variety of major labels. Thus far they’ve managed to block access to The Pirate Bay, Kat.ph, H33T and Fenopy, and preparations are being made to add many others.

The effectiveness of these initial measures has been called into doubt, as they are relatively easy to bypass. For example, in response to the blockades hundreds of proxy sites popped up, allowing subscribers to reach the prohibited sites via a detour.
However, as of this week these proxies are also covered by the same blocklist they aim to circumvent, without a new court ruling.

The High Court orders give music industry group BPI the authority to add sites to the blocklist without oversight. Until now some small changes have been made, mostly in response to The Pirate Bay’s domain hopping endeavors, but with the latest blocklist update a whole new range of websites is being targeted.

Music firms secure orders blocking access to Pirate Bay - Crime & Law News from Ireland & Abroad | The Irish Times - Wed, Jun 12, 2013
Four major music companies have secured court orders requiring six internet service providers to block access by subscribers to various Pirate Bay websites within some 30 days in a bid to prevent illegal downloading of copyright music and other material. [...]

Today, Mr Justice Brian McGovern said he was satisfied to make the order in circumstances including that new copyright laws here and in the EU permitted such orders to be made. He said he fully agreed with a previous High Court judge who had said he would make such blocking orders if the law permitted and noted the law now allowed for such orders. The form of the orders means the music companies will not have to make fresh applications to court if Pirate Bay changes its location on the internet.

Did Conroy’s AFP filter wrongly block 1,200 sites?
Looks like many Aussie network operators were legally required to block 1,200 websites (presumably, one target and 1199 false positives), in secret.

Quoting http://lists.ausnog.net/pipermail/ausnog/2013-April/017993.html : "You get a notice to
block. You block or either get fined, go to jail or lose your carrier
licence. It is a blunt instrument and it is a condition of being at 'the
big boys table' i.e. you're a carrier or a carriage service provider."

Danish Police Censor Google, Facebook and 8,000 Other Sites by Accident | TorrentFreak
'Lundberg said that his organization was sorry for the mistake and has now adopted a new system whereby blocked sites have to now be approved by two employees instead of one, although why that was not the case already for such a serious process is up for debate. The other question is how at the flick of a switch do 8,000 sites suddenly get added to a blacklist – for whatever reason – without any kind of oversight. Denmark’s IT-Political Association is critical and has called for ISPs to cease cooperation with the voluntary scheme which operates without any kind of judicial review. “Today’s story shows that the police are not able to secure against manual errors that could escalate into something that actually works as a ‘kill switch’ for the Internet,” the group said in a statement.'

Adrian Weckler confims that "Ireland's SOPA" will be vague and open-ended
'The clear implication from [Adrian's] interview with Sean Sherlock is that the proposed measures will be lacking in any real detail, leaving it entirely up to the judges as to what types of blocking might emerge. (Possibly going beyond web blocking to also target hosting and other services.) This ambiguity -- as well as jeopardising fundamental rights -- will create intolerable uncertainty for businesses such as Google who might find themselves at risk of business threatening and unpredictable injunctions and will certainly deter others from setting up in Ireland.' -- this is much, much worse than I thought, particularly given the level of technical knowledge among Ireland's judges (if Mr. Justice Charleton's performance in EMI v. UPC is anything to go by).

Daragh O'Brien on the Gardai's plans to force ISPs to implement IP filtering
'Internet blocking is ineffective. The current proposal lacks sufficient checks and balances, and may even require ISPs and telcos to break other laws to comply. It will inevitably result in innocents being tarred as offenders. Data Protection principles (such as “Adequate, Relevant, and Not Excessive” are being blatantly ignored to implement an ineffective solution. Far better is to shut down the shop by removing the images at source and invest time, energy, and resources into a more transparent effort to manage this issue.' well said

Putting up barriers to a free and open internet - The Irish Times
Ireland's Dept of Justice is investigating setting up a "Great Firewall" filtering the country's internet, a la China and Australia. “Blocking involves censorship taken on no legal basis. There is no judge, no jury and no right to be heard if you are blocked,” says [DRI's TJ] McIntyre. “The chances are it also will be used in unaccountable ways by unaccountable organisations.”
