কি করবেন যদি ইউটিউব বা ফেইসবুকের মত সাইট ব্লক করে দেয়া হয়?

কিছুদিন আগে বাংলাদেশের মানুষ এক নতুন আভিজ্ঞতার সন্মুখীন হয়েছিলেন আর তা হচ্ছে ইউটিউবের মত সাইটে প্রবেশ করতে না পারা। শুধু বাংলাদেশ নয়, বিশ্বের অনেক দেশের মানুষই এই সমস্যার সন্মুখীন হন। বিশেষ করে চীনে এই ধরনের সমস্যায় প্রতিনিয়তই পড়তে হয়। চীনে ইউটিউব বন্ধ আছে বেশ অনেক দিন ধরেই। ইউটিউব ছাড়াও আরো অনেক সাইটেই চীন থেকে প্রবেশ করা যায়না। এছাড়া সিরিয়া সহ আরও অনেক আরব দেশেই বন্ধ করে দেয়া হয়েছে ফেইসবুক। তাহলে সমাধান কি ?
অনেক প্রক্সি সাইট আছে যেখানে আপনার কাঙ্ক্ষিত সাইটের URL টি লিখে আপনি সেই সাইটে প্রবেশ করতে পারবেন। কিন্তু এসব প্রক্সি সাইট থেকে ইউটিউবের মত ভিডিও শেয়ারিং সাইটে প্রবেশ করা যায় ঠিকই কিন্তু ভিডিও দেখা যায়না।
তাহলে আরো ভাল সমাধান কি?
আমার মতে সবচেয়ে ভাল সমাধান হচ্ছে “ফ্রী গেইট”। মাত্র ৪১০কিলোবাইটের ছোট্ট একটি সফটওয়্যার।

সফটওয়্যারটি এখান থেকে আপনার কম্পিউটারে ডাউনলোড করুন। URL: http://download.cnet.com/Freegate/3000-2085_4-10415391.html তারপর রান করুন। সফল ভাবে রান হলে সফটওয়্যারটি নিচের ছবির মতো দেখাবে।

রান করার সাথে সাথে ইন্টারনেট এক্সপ্লোরার খুলবে। এবার সাধারন ভাবেই ইন্টারনেট এক্সপ্লোরারের এড্রেস বারে ওয়েবসাইটের ঠিকানা লিখে যেকোন সাইটে প্রবেশ করতে পারবেন।
সতর্কতাঃ  কম্পিউটার বন্ধ করার আগে সফটওয়্যারটি অবশ্যই বন্ধ করে নিন।
টিপসঃ  সফটওয়্যারটি বন্ধ না চালু অবস্থায় যদি ইন্টারনেট এক্সপ্লরার ঠিক মত কাজ না করে, তাহলে সফটওয়্যারটি বন্ধ করে আবার চালু করলেই সব ঠিক হয়ে যাবে।

Submarine cable repair to slow down internet

Submarine cable repair to slow down internet

Bangladesh is set to experience problematic internet connection, as repair work began on its fibre optic backbone Sunday. An official of Bangladesh Telecommunication Company Ltd (BTCL) said, "The interruption has started after the arrival of a ship to repair the cable. It will be fixed by May 31." Due to prior information about maintenance, users of BTCL and several other internet providers were prepared to handle the problem. But clients of some internet service providers (ISPs) might face interruptions, he added.

Broadband poised for a leap

Bangladesh's slowly advancing broadband market is expected to flourish with affordable rates for the masses, as the telecom minister assured prospective licensees that the 3G spectrum will not be auctioned.
The minister's assurance however raised mixed responses among telecom industry insiders, as no one is sure about the criteria of the "beauty contest", which is expected to become a tool for awarding the 3G (third generation) licences. Traditionally, beauty contests incorporate personality, talent and answers to judges' questions as criteria for selection. In response to journalists' queries, Telecom Minister Rajiuddin Ahmed Raju recently said: "The 3G licence will not be auctioned as was happened with the WiMax licence, which was awarded at a hefty price of Tk 215 crore."
Bangladesh's internet penetration rate may reach 32 percent at household level and 66 percent at business level by 2020, according to a study conducted by Boston Consulting Group (BCG), USA. At present, the average internet penetration rate is only 4 percent, which is mainly driven by mobile operators' EDGE (enhanced data rates for global evolution) and GPRS (general packet radio service) solutions. All the mobile operators are ready to upgrade their networks to 3G from the existing 2.5G or 2.75G as 3G is considered one of the most competitive tools to provide high-speed internet. The telecom regulator has already reserved 40 MHz spectrums to allocate to four prospective operators.
"We welcome the telecom minister's comment on arranging a beauty contest to award the 3G licence, rather than monetary bidding," said Ahmed Abou Doma, chief executive officer of Banglalink. He said this is exactly what happened in many advanced countries that have already launched 3G. "They implied the beauty contest approach because it ensures fastest and widest 3G coverage along with the highest service levels and quality for the customers," Doma said.
However, the market's top player -- Grameenphone (GP) -- has doubts about the transparency of the 'beauty contest'. “I don't have details on the exact model or form of the 'beauty contest' that the telecom ministry and the regulator have talked about. Therefore, it's difficult to accept or reject the idea. It may be noted that beauty contests are inherently a non-transparent process," said Oddvar Hesjedal, chief executive officer of Grameenphone Ltd.
Hesjedal, however, said it might be considered if the 'beauty criteria' are wide enough to include all mobile players in Bangladesh and all the terms and conditions of spectrum allocation are affordable to all the existing operators. "GP will support any process, which is credible and transparent," he said. He suggested the regulator proceed with public knowledge and go for an open consultation before launching the model. "In any process, we must not forget the ultimate objective of providing affordable mobile broadband and modern services," said Hesjedal.
Among the six operators, five GSM (global system of mobile communication) operators are technically eligible for the 3G spectrum. Except for CDMA (code division multiple access) technology-based Citycell, Grameenphone, Banglalink, Robi and Warid will contest for the 3G spectrum. However, state-run Teletalk may enjoy a privilege in getting the 3G spectrum without participating in the 'beauty contest'. "Nothing has been decided yet," said Zia Ahmed, chairman of Bangladesh Telecommunication Regulatory Commission (BTRC), the regulator. "We are working on finalising the guideline for 3G."
In Bangladesh, only 4.4 million people have access to the internet. Forty-eight percent of urban Bangladesh is aware of internet services, while 29 percent of the rural population have heard about the service, said the BCG study. Bangladesh will have around 20 million internet subscribers by 2020 if proper policy support is provided, and 90 percent of the users will be added through wireless connections, the study said. Annual earnings from broadband internet penetration in Bangladesh is expected to reach Tk 128 billion by 2020 if the country ensures a rule-based policy regime, according to the US-based consulting group.

Slow Internet?…this is the problem area


The South East Asia-Middle East-West Europe 4 (SEA-ME-WE 4) Submarine Cable is an approximately 18,800 KM long cable connecting Singapore, Malaysia, Thailand, Bangladesh, India, Sri Lanka, Pakistan, United Arab Emirates, Saudi Arabia, Egypt, Italy, Tunisia, Algeria and France. The system is using Terabit DWDM technology to achieve Maximum bandwidth with minimal cost.
The slowness in the internet is due to damage in the cable between Egypt and France. The restoration work will be progressive taking upto 10-15 days. This has affected countries from Egypt, GCC countries to countries in the Indian sub-continent.

Bangladesh’s internet connectivity was restored to its full capacity at 2:00pm on Sunday.
A fault in a submarine cable on April 14 resulted in Bangladesh losing all its internet communication with countries to the west of the cable including Europe.
The fault was repaired by Mango Teleservices Limited, an International Internet Gateway operator in Bangladesh. The company said in a press release the problem was detected in the cable between Alexandria and Marseilles.

A senior official at the BTCL’s submarine cable project had told bdnews24.com on April 15 that a short circuit at the Italian landing station at Palermo had caused the problem.
On December 21, 2008 Bangladesh faced a similar kind of connectivity disruption, which was restored after 18 hours.

Bangladesh Shut 3 telecom Company – What is the fault of Customer?Isn,t It bad Governance?


WHO IS CARING PUBLIC INTEREST ?
Bangladesh Telecommunication Regulatory Commission (BTRC) yesterday shut down all operations of National Phone for its alleged involvement in illegal VoIP (Voice over Internet Protocol) business.

I knew a person who is user of  Rankstel , last before t2wo days he get his internet connection down,,,, When he inquire he get the companies shut by Government. He consider himself as a general people of Bangladesh . He is really disappointed.

Nothing New in the execution exercise of Bangladesh Govt to do such a irritating steps,Government have to understand here there is investment ,Public Involvement ,Public Interest.

Only one asking is that How can a political Govt -Govern in such way where there is public interest.I don’t disagree for the punishment of illegal operation of VoiP but is it the way? There is no notice – no case -no nothing. So such a british colonial style of Governance is not acceptable to the general people.
All Govt Administrator must change attitude of BRITISH COLONIAL ADMIN. My urge to BTRC- if the companies are involved in VoiP fine them. If our Constitution allow .

If the decision come to shut please confirm the re middy for customer and let it done then it can be appreciated

Otherwise it can cause LOTS OF HARM TO THE NATIONAL INVESTMENT RELIABILITY .
News:
Bangladesh Telecommunication Regulatory Commission (BTRC) yesterday shut down all operations of National Phone for its alleged involvement in illegal VoIP (Voice over Internet Protocol) business.
It was the third telephone company to be caught in BRTC’s drive against illegal VoIP operations in a week.
