This behavior could go unnoticed over the legacy HTTP&amp;#x2F;1.1 connections due to browsers opening a hugh number of connections (~20) to a host, so when one would fail it wouldn&amp;#x27;t block everything.</text><parent_chain></parent_chain></comment><story><title>Employing QUIC Protocol to Optimize Uber’s App Performance</title><url>https://eng.uber.com/employing-quic-protocol/</url></story>

Successfully shifting 80% of mobile traffic to QUIC for a 50% reduction in latency is amazing. QUIC and the ongoing work with multipath TCP&amp;#x2F;QUIC will be huge QoL improvements for mobile networking.</text><parent_chain></parent_chain></comment><story><title>Employing QUIC Protocol to Optimize Uber’s App Performance</title><url>https://eng.uber.com/employing-quic-protocol/</url></story>
