Internet Connectivity: Today, the internet is not just a source of entertainment, but has become a vital part of banking, communication, education, and security. When an entire country or a large area suddenly goes offline, it raises the question of how governments can so easily block internet connectivity. The reality is that both technical and legal mechanisms are at play.
The most common way to shut down the Internet
Governments typically order telecom companies to shut down internet services. All mobile network and broadband service providers in the country operate under government directives. Upon receiving orders, companies block mobile data, broadband, or both within minutes. This leads to widespread internet outages.
How DNS and IP blocking stop the internet
Sometimes, instead of shutting down the entire internet, governments block specific websites or platforms. DNS blocking or IP blocking is used to do this. When a user tries to access a website, their request simply doesn't reach the server. Social media, messaging apps, or news websites are blocked using this method.
Mobile network is down, but why are calls still working?
It's often seen that the internet is shut down, but calling and SMS services remain operational. This is because voice and data services operate on separate systems in mobile networks. The government issues instructions to shut down only data services when necessary to curb rumors and online activity, while ensuring essential calling services remain available.
The role of undersea cable and gateway control
In some countries, governments also control international internet gateways. Undersea internet cables and international gateways are the key to accessing the global internet. By controlling these gateways, governments can completely cut off external internet access, effectively taking the country almost completely offline.
Internet shutdowns in the name of law and security
Most internet shutdowns are imposed in the name of law and order, national security, or emergencies. During riots, protests, or sensitive situations, governments recognize that the internet can become a major source of rumors. Therefore, connectivity is blocked as a precautionary measure.
What impact does it have on common people?
Internet outages directly impact online payments, office work, education, and business. In an era of initiatives like Digital India, internet shutdowns disrupt the daily lives of ordinary people.
