Internet: Internet has become an important part of our life in today’s digital world. Everything from work to education, entertainment to banking is dependent on the Internet. But you must have heard or experienced many times that suddenly the internet of an entire city stops simultaneously. After all, how does this happen and which technology works behind it, let us know.
Spine of Internet Network
The Internet mainly runs through fiber optic cables. These cables are laid within the ground or under the sea and transport millions of data packets from one place to another. When these cables are cut due to some reason, they get spoiled or intentionally closed, then the internet of the entire area may come to a standstill.
Internet shutdown technology
Governments or network providers can close the Internet technically whenever they want. Internet shutdown technology is used for this. Two major methods are adopted in this:
IP blocking (IP blocking): Access of a particular website, app or service is blocked so that people do not reach it.
Kill Switch (Kill Switch): This technique shuts down the entire network simultaneously. Signals are cut off from the control system with telecom companies and immediately stops working internet.
Why is the internet shutdown done?
Many times governments shut down the internet of the entire city to maintain law and order or prevent rumors. For example, there is a higher risk of spreading rumors during choice, performance or any major festival. In such a situation, the Internet shutdown is applied as a “security measure”. On the other hand, technical fault is also a major reason for the internet shutting down. Such as server down in a big data center, power problem, cyber attack, or cable cutting events.
What is the effect?
- The closure of the internet of the entire city affects the everyday life of common people.
- Online payments stop.
- Digital class and work from home are interrupted.
- The pressure on hospitals and emergency services increases.
- Business and business suffers a big loss.
What is the solution?
According to experts, controlled access or partial restrictions are a better option rather than completely shutting down the Internet. For example, blocking social media apps only temporarily so that rumors do not spread, but necessary services remain on. Also, the incidents of internet shutdown can be prevented to a great extent due to technical flaws by strengthening cyber security and securing network infrastructure.
