Cloudflare uses lava lamps to provide random data for secure SSL/TLS encryption. Randomness is crucial in encryption to prevent predictability and make encrypted data more secure. The lava lamps in the Cloudflare headquarters serve as a source of truly random data, which is used as a cryptographic seed in a cryptographically
