  "account": "Google's QUIC and HTTP/3 protocols aim to solve the problem of Head-of-Line-Blocking, a performance issue caused by the 40-year-old TCP protocol. QUIC uses UDP instead of TCP, allowing for independent streams and reducing the impact of lost packets. This results in faster website loading times, especially on slow connections and mobile networks. Major browsers and web servers now support HTTP/3, but administrators and developers need to ensure their infrastructure is compatible, including updating firewalls and load balancers to allow UDP traffic on port 443.",
  "summary": "QUIC & HTTP/3: Das Ende von TCP? So funktioniert die neue Web-Protokoll-Ära Wenn du jemals auf eine Website geklickt hast und gesehen hast, wie der Browser minutenlang läd – während der Browser-Fortschrittsbalken fast leer bleibt –, dann kennst du das Problem des Head-of-Line-Blocking . Es ist der stille Performance-Killer im Internet, und es liegt an einem Protokoll, das schon länger als 40…",
