Cloudflare has found that 20% of all internet connections are abruptly closed before any useful data can be exchanged, suggesting intentional tampering by third parties. The company's global network allows it to identify patterns that suggest external tampering with a connection to prevent content from being accessed. Connection tampering is often hard to decipher but the ways connections are abruptly closed give clues to what might have happened. Cloudflare has shared a view of global connection tampering practices and launched a new dashboard and API on Cloudflare Radar that shows a near real-time view of specific connection timeout and reset events experienced by users connecting to its network globally.
