Re: Pak Ke Internet Ke TAAR Katt Gai

Electricity is less than 40% then why you need 100% internet speed???


because there's a thing called DOWNLOADING :P

torrents downloading speed has been affected the most....its as slow as 100 KB/sec where it used to be atleast 500-600 KB/sec :((cry)

ایک لطیفہ یاد آگیا۔

ایک پارک میں ایک انگریز لیپ ٹاپ لے کر بیٹھا ہوا تھا اور اس کے برابر میں ایک پاکستانی خالی ہاتھ بیٹھا ہوا تھا۔
انگریز نے کہا کہ ہم لوگ اتنی ترقی کر چکے ہیں، پوری دنیا ہماری نظروں کے سامنے ہے، تم لوگوں نے کیا کیا اب تک؟
پاکستانی نے کہا، بلند بلند دعوے مت کر۔
انگریز نے کہا میں ثابت کر سکتا ہوں۔
پاکستانی: تو ایسا کرتے ہیں کہ میں ایک سوال پوچھتا ہوں اگر وہ تمہیں نہ آیا تو تم مجھے 2 ہزار روپیہ دینا اور پھر تم مجھ سے سوال پوچھنا اگر وہ مجھے نہ آیا تو میں تمہیں 500 روپیہ دونگا۔
انگریز مان گیا۔
انگریز نے سوال کیا، بتاؤ زمین کے علاوہ کس سیارے پر زندگی کے امکانات ہیں؟
پاکستانی خاموش رہا
انگیز نے کہا وہ سیارہ مریخ ہے۔
اب پاکستانی نے سوال کیا: بتؤ وہ کونسا جانور ہے جو پہاڑ پر جاتا ہے تو چار ٹانگیں ہوتی ہیں، واپس آتا ہے تو تین ٹانگیں ہوتی ہیں۔
انگریز نے کافی دیر انٹر نیٹ پر سرچ کیا فون ملائے، جواب نہ دے سکا تو 2 ہزار روپیہ پاکستانی کو دیئے اور کہا: مجھے جواب نہیں معلوم۔
پاکستانی نے ان دو ہزار میں سے 500 کا نوٹ واپس انگریز کو دیا اور کہا: مجھے بھی نہیں معلوم :)۔

Under Sea Cable Cut Slows Down Internet Across Pakistan

SMW4, one of the four undersea internet cables that connects Pakistan to rest of the world, has been damaged in the segment 4 beyond Egypt for currently unknown reasons, impacting the internet speeds for majority of internet users with-in Pakistan.
This is second undersea cable that got damaged in parallel, resulting into serious browsing issues for Pakistani internet users.
The Estimated Time To Repair (ETTR) has not been announced as of yet, as PTCL and Transworld, the two lessees of the cable for Pakistan are in communication with SEAMEWE-4 consortium members to determine the time it will take to repair the cable.
Internet service providers estimates that around 40% of customers may experience slow browsing.
ISPs said that majority of internet traffic is already shifted to SMW3.
It merits mentioning here that other undersea backhaul data and voice cables namely IMEWE and EIG are also being repaired as they were damaged earlier this month.
South East AsiaMiddle EastWestern Europe 4 (SEA-ME-WE 4) is an optical fibre submarine communications cable system that carries telecommunications between Singapore, Malaysia, Thailand, Bangladesh, India, Sri Lanka, Pakistan, United Arab Emirates, Saudi Arabia, Sudan, Egypt, Italy, Tunisia, Algeria and France.
The cable is approximately 18,800 kilometres long, and provides the primary Internet backbone between South East Asia, the Indian subcontinent, the Middle East and Europe.

Global internet slows after 'biggest attack in history' - BBC

Existence-of-Cyber-Warfare-Unit-Confirmed-by-German-Authorities.png


The internet around the world has been slowed down in what security experts are describing as the biggest cyber-attack in history.


A row between a spam-fighting group and hosting firm has sparked retaliation attacks flooding core infrastructure.
It is having an impact on widely used services like Netflix - and experts worry it could escalate to affect banking and email services.
Five national cyber-police-forces are investigating the attacks.


Spamhaus, a group based in both London and Geneva, is a non-profit organisation which aims to help email providers filter out spam and other unwanted content.



To do this, the group maintains a number of blocklists - a database of servers known to be being used for malicious purposes.

Recently, Spamhaus blocked servers maintained by Cyberbunker, a Dutch web host which states it will host anything with the exception of child pornography or terrorism-related material.


Sven Olaf Kamphuis, who claims to be a spokesman for Cyberbunker, said, in a message, that Spamhaus was abusing its position, and should not be allowed to decide "what goes and does not go on the internet".



Spamhaus has alleged that Cyberbunker, in cooperation with "criminal gangs" from Eastern Europe and Russia, is behind the attack.

Cyberbunker has as yet offered no reply to the BBC when contacted directly.


'Immense job'
Steve Linford, chief executive for Spamhaus, told the BBC the scale of the attack was unprecedented.
"We've been under this cyber-attack for well over a week.

'


"But we're up - they haven't been able to knock us down. Our engineers are doing an immense job in keeping it up - this sort of attack would take down pretty much anything else."


Mr Linford told the BBC that the attack was being investigated by five different national cyber-police-forces around the world, but said he was unable to disclose more details as the forces in question were concerned that they too may suffer attacks on their own infrastructure.



The attackers have used a tactic known as Distributed Denial of Service (DDoS), which floods the intended target with large amounts of traffic in an attempt to render it unreachable.



In this case, Spamhaus's Domain Name System (DNS) servers were targeted - the infrastructure that joins domain names, such as bbc.co.uk, the website's numerical internet protocol address.



Mr Linford said the attack's power would be strong enough to take down government internet infrastructure.


"If you aimed this at Downing Street they would be down instantly," he said. "They would be completely off the internet."

He added: "These attacks are peaking at 300 gb/s (gigabits per second).


"Normally when there are attacks against major banks, we're talking about 50 gb/s."


Clogged-up motorway
The knock-on effect is hurting internet services globally, said Prof Alan Woodward, a cybersecurity expert at the University of Surrey.

"If you imagine it as a motorway, attacks try and put enough traffic on there to clog up the on and off ramps," he told the BBC.



"With this attack, there's so much traffic it's clogging up the motorway itself."



Spamhaus is able to cope, the group says, as it has highly distributed infrastructure in a number of countries.


The group is supported by many of the world's largest internet companies who rely on it to filter unwanted material.


Mr Linford told the BBC that several companies, such as Google, had made their resources available to help "absorb all of this traffic".

The attacks typically happened in intermittent bursts of high activity.


"They are targeting every part of the internet infrastructure that they feel can be brought down," Mr Linford said.

"We can't be brought down.


"Spamhaus has more than 80 servers around the world. We've built the biggest DNS server around."

Inside the Biggest Cyberattack in History

cyberattacks.jpg




Alex Fitzpatrick


A cyberattack originally targeting a single company is now being described by experts as one of the biggest attacks in Internet history. The assault, which recently began impacting elements of the Internet's physical infrastructure, has been dragging down Internet speeds across the world and particularly in Europe but what makes this type of attack different from all other attacks?

First, some background: The attacks originally targeted a European anti-spam company called Spamhaus, which blacklists what it considers sources of email spam and sells those blacklists to Internet Service Providers. The attack began early last week as waves of large but typical Distributed Denial of Service (DDoS) assaults shortly after Spamhaus blacklisted Cyberbunker, a controversial web hosting company. Cyberbunker has not directly taken responsibility for the attacks against Spamhaus.

In a common DDoS attack, hackers use thousands of computers to send bogus traffic at a particular server in the hopes of overloading it. The computers involved in DDoS attacks have often been previously infected with malware that gave a hacker control of the machine without the legitimate owner's knowledge. Hackers use malware (often sent via email spam) to amass large networks of infected computers, called "botnets," for DDoS operations and other purposes.

Spamhaus contracted with security firm CloudFlare to help mitigate the attacks soon after they began. CloudFlare has been defending Spamhaus by spreading the attacks across multiple data centers, a technique that can keep a website online even if it's hit by the maximum amount of traffic a typical DDoS can generate.

"Usually these DDoS attacks have kind of a natural cap in their size, which is around 100 gigabits per second,"

CloudFlare CEO Matthew Prince told Mashablebefore explaining the limitation in typical DDoS attack size is due to routing hardware limitations.

These attacks, however, have evolved into a complex and ferocious beast, pointing up to 300 gigabits per second at an expanding list of targets. How?

After the hackers realized they couldn't knock Spamhaus offline while it was protected by CloudFlare, they chose a different tactic: targeting CloudFlare's own network providers by exploiting a known fault in the Domain Name System (DNS), a key piece of Internet infrastructure.

"The interesting thing is they stopping going after us directly and they started going after all of the steps upstream from us," said Prince.


"The interesting thing is they stopping going after us directly and they started going after all of the steps upstream from us," said Prince."Going after our immediate transit providers, then going after their transit providers."

DNS essentially turns what humans type into an address bar ("www.mashable.com") to the desired website's IP address and helps to deliver the desired Internet content to a user's computer. An essential element of the DNS system are DNS resolvers 21.7 million of which are open and able to be found and manipulated by hackers.
"The attack works by the attacker spoofing the victim's IP address, sending a request to an open resolver and that resolver reflecting back a much larger response [to the victim], which then amplifies the attack," said Prince. A detailed technical explanation is available on CloudFlare's blog.

Because DNS resolvers are connected to large pipes with plenty of bandwidth to point at a target, hackers can manipulate them to amplify standard DDoS attacks from a maximum of about 100 gigabits per second to the neighborhood of 300 gigabits per second.

Prince toldMashable these attacks have been "certainly the largest attacks we've seen."

Prince told Mashable these attacks have been "certainly the largest attacks we've seen."

"And we've seen what we thought were some big attacks," he added. Kaspersky Labs, a leading security research group, called it "one of the largest DDoS operations to date."

What can be done about preventing these specialized DDoS attacks? First, said Prince, Internet Service Providers should implement technologies that prevent hackers from spoofing victims' IP addresses. Second, network administrators need to close any and all open DNS resolvers running on their network.

"Anyone that's running a network needs to go to openresolverproject.org, type in the IP addresses of their network and see if they're running an open resolver on their network," said Prince. "Because if they are, they're being used by criminals in order to launch attacks online. And it's incumbent on anyone running a network to make sure they are not wittingly aiding in the destruction of the Internet."

If there's a silver lining to these continued attacks, it's that they have likely motivated the security industry, which has been talking about, but taken apparently insufficient action on, the open DNS issue for some time. Prince, however, warns DNS-amplified DDoS attacks won't be going away any time soon.

"The good news about an attack like this is that it's really woken up a lot of the networking industry and these things that have been talked about for quite some time are now being implemented," said Prince.

"There was some progress on shutting down open resolvers before," he added later. "I think that's going to be a constant process this is a problem that we're going to have to live with for the next several years."

When I was in the US, nothing in the world could upset that country's internet. Simply because most of the internet is hosted in US. The whole world's internet problems simply didn't matter. Aah yes... Janat-ul-America... what beautiful days.
