Understanding India's Internet Censorship Regime
Introduction
India is the world's second-largest internet user base — with over 900 million users — yet the experience of accessing the internet varies significantly depending on one's Internet Service Provider (ISP). Website blocking in India is governed by Sections 69A and 79 of the Information Technology Act, 2000, but implementation is inconsistent, opaque, and largely unaccountable. A 2025 study testing 294 million domains across six major ISPs found that of 43,083 blocked domains, only 1,414 were blocked uniformly — raising serious questions about rule of law, digital rights, and internet governance.
"In the absence of a standardised framework or guidelines, ISPs are left to their own devices, resulting in an inconsistent blocking landscape."
| Indicator | Data |
|---|---|
| Total domains tested (2025 study) | 294 million |
| Total blocked domains found | 43,083 |
| Domains blocked by all 6 ISPs uniformly | 1,414 (3.3%) |
| ISPs surveyed | 6 major and regional ISPs |
| Primary blocking method used | DNS poisoning |
| Legal authority for blocking | IT Act Sections 69A and 79 |
Legal Framework for Website Blocking
Section 69A — IT Act, 2000: Empowers the Central Government to direct any intermediary or ISP to block public access to online content in the interest of sovereignty, security, public order, or prevention of incitement. Blocking orders are issued confidentially — ISPs are legally bound not to disclose them.
Section 79 — IT Act, 2000: Provides safe harbour to intermediaries for third-party content, conditional on compliance with government takedown and blocking directions.
ISP Licensing Agreement: Explicitly requires ISPs to block internet sites as identified and directed by the licensor — making compliance mandatory but leaving implementation methods to ISP discretion.
Shreya Singhal v. Union of India (2015): Supreme Court struck down Section 66A of the IT Act as unconstitutional; upheld Section 69A but mandated procedural safeguards — including written orders and an opportunity to be heard. Transparency in implementation however remains absent.
How DNS Blocking Works
When an ISP receives a blocking order, it may implement it through multiple technical protocols. Most Indian ISPs use DNS poisoning as the primary method — it is cheap, requires no deep packet inspection, and is easy to deploy at scale.
DNS (Domain Name System): Translates domain names (example.com) into IP addresses browsers can access. When an ISP blocks at DNS level, its servers return a false address — redirecting the user away from the actual website. This technique is easily bypassed using alternate DNS servers or VPNs — raising questions about both effectiveness and proportionality.
Key Findings — Inconsistency in Blocking
| Content Category | Blocking Consistency Across ISPs |
|---|---|
| Piracy and peer-to-peer file sharing | Inconsistent |
| Pornography and gambling | Inconsistent |
| Terrorism and militancy content | High consistency |
| China's Weibo.com | Perfect consensus |
| The Kashmir Walla (Srinagar publication) | Perfect consensus |
The data reveals a two-tier blocking regime in practice:
- Politically and security-sensitive domains receive near-perfect enforcement across all ISPs
- Legally mandated blocks (piracy, obscenity) are enforced unevenly — suggesting ISPs treat orders selectively based on perceived sensitivity rather than legal obligation
Almost all ISPs also engage in some form of arbitrary blocking — domains blocked without any clear legal order — indicating accountability gaps beyond mere inconsistency.
Governance and Rights Concerns
1. Opacity of the Regime Blocking orders under Section 69A are confidential. Users receive no notification when a website is blocked or why. There is no public blocklist — making judicial or civil society oversight structurally impossible.
2. Absence of Standardised Framework No uniform technical or procedural guidelines govern how ISPs implement blocking orders. The result is a fragmented internet where access to the same content varies by ISP — undermining the principle of a uniform rule of law.
3. Arbitrary Blocking ISP-level arbitrary blocking — beyond government orders — occurs with no legal basis and no accountability mechanism.
4. Freedom of Expression (Article 19(1)(a)) Inconsistent and opaque blocking disproportionately affects access to information. The blocking of a regional press publication like The Kashmir Walla with the same uniformity as national security threats raises concerns about misuse of blocking powers against press freedom.
5. Digital Divide Amplified Users unaware of VPNs or alternate DNS configurations — predominantly lower-income and less digitally literate populations — bear the full effect of blocking, while technically sophisticated users bypass it easily. This creates an unequal information environment along class lines.
Comparative Perspective
| Country | Blocking Transparency |
|---|---|
| European Union | DSA mandates transparency reports on content removals |
| USA | No mandatory blocking; court orders publicly accessible |
| India | Blocking orders confidential; no public disclosure |
| China | Comprehensive blocking with no pretence of transparency |
India's regime sits in an uncomfortable middle — legally structured unlike China, but lacking the transparency accountability of democratic peers.
Way Forward
- Publish a public blocklist of blocked domains with stated legal basis — with carve-outs only for child sexual abuse material and active national security operations
- Issue standardised technical guidelines to ISPs for implementing blocking orders uniformly across all protocols
- Establish an independent oversight mechanism — parliamentary committee or ombudsman — to review blocking orders periodically
- Mandate user notification when access to a domain is blocked, including the legal provision invoked
- Strengthen judicial review of blocking orders by ensuring affected parties — website operators and publishers — have a timely opportunity to challenge orders
- Revisit ISP licensing conditions to prohibit arbitrary blocking beyond government-mandated orders
Conclusion
India's internet blocking regime is legally grounded but operationally chaotic — inconsistent across providers, opaque to users, and structurally unaccountable. A state that blocks 43,000 domains with uniform enforcement on only 3.3% of them is not administering law — it is administering discretion. The right to access information, integral to Article 19(1)(a), cannot be meaningful in a system where what one can read depends on which ISP one subscribes to. Transparency, standardisation, and independent oversight are not concessions to free expression — they are the minimum conditions for a legitimate, rule-of-law-based digital governance framework.

What is the legal and institutional framework governing website blocking by ISPs in India?
Institutional Mechanism: ISPs operate under licensing agreements which explicitly require them to block websites as directed by the government (licensor). These orders are typically confidential, meaning ISPs cannot disclose details about blocked content. This creates a system where implementation is mandatory but not transparent.
Implications: While this framework ensures state control over harmful or unlawful content, it also raises concerns regarding transparency, accountability, and potential misuse. The absence of public disclosure mechanisms limits judicial and public scrutiny. For example, the blocking of platforms like Weibo or publications such as The Kashmir Walla reflects how certain sensitive cases receive strict enforcement, highlighting selective prioritization within the system.
How do Internet Service Providers technically implement website blocking in India?
DNS Poisoning: When a user tries to access a website, the DNS translates the domain name into an IP address. ISPs manipulate this process by returning incorrect IP addresses, a method known as DNS poisoning. As a result, users are redirected away from the intended website.
Limitations and Alternatives: While DNS blocking is efficient, it is also relatively easy to bypass using VPNs or alternative DNS servers. More advanced methods like Deep Packet Inspection (DPI) can offer stricter enforcement but are costlier and raise privacy concerns.
Example: Many piracy or gambling websites are blocked via DNS filtering, but users often access them through VPNs, indicating the limitations of current technical approaches.
Why is there inconsistency in website blocking across different ISPs in India?
Reasons for Inconsistency:
- Lack of Standardized Guidelines: There is no uniform protocol dictating how ISPs should implement blocking orders.
- Technical Discretion: ISPs can choose different blocking methods (DNS, HTTP, TLS), leading to varied outcomes.
- Resource Constraints: Smaller ISPs may lack advanced infrastructure for comprehensive enforcement.
Selective Enforcement: Sensitive content such as terrorism-related material tends to have higher consistency, while categories like piracy or gambling show greater variation.
Implications: This inconsistency undermines the principle of equal access to information and creates a fragmented Internet experience, where access depends on the ISP rather than uniform national policy.
Critically analyze the challenges posed by the current website blocking regime in India.
Inconsistency and Arbitrariness: As studies show, ISPs do not uniformly implement blocking orders, leading to arbitrary censorship. This raises concerns about rule of law and fairness, as users on different networks experience different levels of access.
Impact on Fundamental Rights: Website blocking can affect the freedom of speech and expression (Article 19(1)(a)). Without transparent procedures or appeal mechanisms, there is a risk of overreach and suppression of legitimate content.
Technological Limitations: Reliance on DNS blocking makes enforcement weak and easily bypassable, reducing effectiveness while still imposing restrictions.
Way Forward:
- Establish clear, standardized guidelines for ISPs
- Introduce transparency through public disclosure of blocked domains
- Strengthen judicial oversight and grievance redressal mechanisms
Can you provide examples that illustrate selective enforcement and prioritization in website blocking in India?
Case of Specific Websites: Domains such as Weibo.com and The Kashmir Walla have been consistently blocked across multiple ISPs. These cases indicate that politically or diplomatically sensitive content is treated with stricter enforcement.
Contrast with Other Categories: In comparison, websites related to piracy, gambling, or pornography show inconsistent blocking. Some ISPs block them rigorously, while others do not, indicating lower enforcement priority.
Implications: This selective enforcement suggests that the blocking regime is not purely rule-based but influenced by the perceived sensitivity of content. It raises questions about bias, transparency, and proportionality in decision-making, which are critical for a लोकतांत्रिक (democratic) digital ecosystem.
As a policymaker, how would you design a more transparent and consistent website blocking framework in India?
Key Reforms:
- Standardization: Develop clear technical and procedural guidelines for ISPs to ensure uniform blocking practices.
- Transparency Mechanism: Publish a centralized, regularly updated list of blocked websites, with exceptions for sensitive cases like national security or child protection.
- Judicial Oversight: Introduce independent review mechanisms to assess the necessity and proportionality of blocking orders.
Technological Improvements: Encourage the use of more precise blocking techniques to minimize over-blocking and collateral damage. At the same time, ensure privacy safeguards to prevent misuse of surveillance technologies.
Case-Based Approach: For example, a transparent system similar to the Lumen Database (used globally for content takedown transparency) could be adapted for India.
Outcome: Such reforms would enhance accountability, public trust, and consistency, while maintaining the state's ability to regulate harmful content effectively.
India's internet blocking regime lacks transparency, consistency, and accountability, impacting digital rights and governance.
