Final conclusion
- Growing Reliance on VPNs:
The growing search trends for VPNs across all three countries suggest that internet users are actively seeking ways to bypass censorship. VPN usage is becoming a common tool for accessing blocked content, especially in regions where internet freedom is under threat.
In India, VPN searches correlate with high-profile political events, while in Bangladesh and Sri Lanka, VPN adoption appears to be linked to times of civil unrest, such as protests or elections.
- Geopolitical Influence on Censorship Mechanisms:
The role of Chinese technology companies in the infrastructure of censorship in Sri Lanka, specifically Huawei, has raised concerns. The use of Huawei equipment for content filtering and surveillance may point to deeper geopolitical influences affecting internet governance.
In Bangladesh, Chinese companies like Huawei have been instrumental in shaping the telecommunications infrastructure, which could facilitate more widespread and sophisticated censorship mechanism
3.1 Societal Impacts
The effects of digital censorship extend far beyond the immediate inability to access certain websites. It has broader implications on the rights to free expression, access to information, and social behavior. This section analyzes the societal consequences of censorship in India, Bangladesh, and Sri Lanka, as observed from the data collected.
India:
- Silencing Dissent:
Censorship in India is used as a tool to suppress opposition voices, particularly around politically sensitive events. The blocking of independent media outlets like The Wire and BBC Hindi demonstrates the government’s attempt to curtail freedom of speech. This has created a climate of self-censorship, where media outlets may avoid reporting on certain topics out of fear of being blocked or targeted.
- Polarization of Information:
The government’s control over internet traffic, particularly around elections or protests, contributes to the growing polarization of public discourse. Citizens are increasingly exposed to information that aligns with government narratives, while alternative viewpoints are relegated to the shadows of the internet.
This creates a skewed information ecosystem, where people’s perceptions are shaped by what is accessible, rather than by a diverse range of viewpoints. This can exacerbate social divisions and fuel conflict.
- Youth and Digital Activism:
The younger generation in India, who are heavily reliant on the internet for information, have increasingly turned to VPNs and other methods to bypass censorship. This reflects a growing disillusionment with state-controlled narratives and a shift toward digital activism.
However, digital activism also faces risks. Many youth-driven movements, such as those protesting against government policies or in favor of specific political ideologies, find their digital platforms blocked or throttled. This has led to a decrease in open discourse, as many fear repercussions for expressing dissenting opinions online.
Bangladesh:
- Erosion of Press Freedom:
The use of DNS poisoning to block news outlets critical of the government, such as Prothom Alo, has had a profound impact on press freedom in Bangladesh. Independent media outlets face increasing challenges in providing balanced news coverage, with many being forced to either censor themselves or risk being shut down entirely.
Journalists and activists have also faced harassment and arrest under the guise of national security laws, further stifling free speech. These actions contribute to a chilling effect on media freedom, as journalists may avoid reporting on topics deemed to be sensitive or controversial.
- Civil Disobedience and Protests:
During the student protests and other instances of civil unrest, the throttling of social media and news websites amplified the feeling of isolation among protesters. Many relied on VPNs to stay connected to the outside world and coordinate their movements. However, this reliance on digital tools also exposes protesters to potential state surveillance and digital tracking.
The censorship tactics employed by the government during protests, such as throttling internet speeds, have contributed to the suppression of civil disobedience. Protestors often find themselves unable to share real-time updates, which hinders their ability to garner domestic and international support.
- Economic Consequences:
Censorship in Bangladesh also affects the economy. International businesses looking to operate in Bangladesh face challenges with internet restrictions, as they cannot be sure whether their websites and online services will be accessible to local users. The unpredictability of access can deter investment, slow economic growth, and increase the cost of doing business in the country.
Furthermore, the erosion of digital freedom impacts the e-commerce sector, as businesses that rely on social media marketing or international exposure may find their digital presence restricted.
Sri Lanka:
- Limited Access to Information:
During political crises, such as the 2024 protests, the government’s use of middleboxes and DPI techniques to block or throttle access to news websites significantly limited the public’s ability to access information. Independent journalists faced severe difficulties in publishing real-time updates, while the public was left with limited access to non-governmental viewpoints.
This lack of access to diverse sources of information limits public awareness of key issues, ultimately stifling informed public debate. Citizens’ ability to make decisions based on a comprehensive understanding of events is severely hindered.

Part 1: Data Collection & Sourcing
This section outlines the methodology and tools used to collect real-time data on digital censorship in India, Bangladesh, and Sri Lanka as of February 17, 2025. The data provides insights into the evolving censorship landscape by integrating search trends, traffic analysis, and technical OSINT data.
1.1 Overview
Given the dynamic nature of digital governance, our approach employs various real-time data sources and advanced OSINT tools. The main objectives are to:
Capture Quantitative Trends: Using Google Trends to monitor spikes in searches for circumvention tools like VPNs, which can indicate censorship.
Analyze Traffic & Engagement Fluctuations: Leveraging Similarweb to monitor website traffic changes that suggest censorship measures, such as throttling or blocking.
Technical Surveillance: Using OSINT platforms (OONI Probe, Shodan, and Censys) to detect technical censorship techniques like DNS manipulation and SNI filtering.
This data serves as the foundation for the detailed analysis presented in subsequent parts of the report.
---
1.2 Tools & Sources
Google Trends
Purpose: Track real-time interest in censorship circumvention tools like VPNs, proxies, and Tor.
Data Points:
India: A notable 290% increase in VPN searches during the February 2024 electoral period.
Bangladesh: Similar spikes during periods of civil unrest.
Sri Lanka: A surge in VPN searches during the 2024 economic protests.
Method: Keywords such as “VPN,” “Tor,” and “Proxy” were queried to track search volume trends in real-time across the three countries.
Similarweb
Purpose: Analyze website traffic patterns to detect disruptions caused by censorship measures.
Data Points:
Bangladesh: Traffic drops observed for international news sites during protest events, suggesting selective censorship.
Sri Lanka: Sudden changes in traffic to local news portals coincided with targeted government blocking efforts.
Method: We tracked traffic on sites like BBC, Al Jazeera, and local news outlets, comparing regional traffic disparities to detect censorship.
OSINT Platforms
OONI Probe:
Purpose: Monitor website blocking and network interference such as throttling or DNS poisoning.
Findings:
India: Over 1,200 URLs, including major news sites, were blocked due to SNI filtering.
Bangladesh: WhatsApp and Instagram were throttled during peak protest times.
Shodan & Censys:
Purpose: Identify network-level censorship tools such as DPI devices, middleboxes, and SNI filtering.
Findings:
India: Shodan scans identified SNI filtering used by ISPs like Jio and Airtel.
Sri Lanka: Increased deployment of Chinese-linked censorship middleboxes, identified via Censys.
Method: Specific queries targeting known censorship infrastructure, such as “country:IN port:443 SNI filtering,” were run to detect active censorship.
Policy Reports & Regional Sources
Reports: Cross-referencing data with publications from Freedom House, IFJ, and International IDEA to contextualize legal frameworks and historical censorship patterns in the region.
Local Sources: Government releases and regional news outlets were reviewed to validate OSINT findings and confirm the timeline of censorship events.
