TURN and anycast: making peer connections work globally

Cloudflare has made its TURN server generally available to all users, offering an intermediary solution for maintaining connections during video calls when local networking conditions prevent direct communication between participants. The service works on Cloudflare's anycast network, ensuring global coverage and near-zero latency required by real-time applications. TURN solves connectivity and privacy problems for real-time apps like video or audio calls by predictably relaying traffic between devices while minimizing delay. It also helps determine if a relay server is needed through the ICE protocol. Cloudflare's TURN service offers unparalleled speed, near-zero latency, and scalability due to its presence in over 330 cities worldwide.
