Overview
- X began a phased, country-by-country rollout to signed-in users on Nov. 5, 2026 after already switching logged-out pages and search-indexed pages to the new web app.
- Engineers replaced three separate background servers for people, search crawlers, and link previews with a single server and removed duplicated client code to simplify delivery and reduce latency.
- X’s principal engineer reported the change cut first-post render on slow connections from about 22 seconds to 2.7 seconds, a near tenfold improvement in the company’s measurements.
- The update was tested internally and on lite.x.com with external testers, and security researcher Jane Manchun Wong reported a noticeably snappier, polished experience while independent broad benchmarking remains limited.
- Faster loads should improve access for users on slow networks and help ad delivery and discovery, but the phased rollout means many users will see uneven improvements over the coming weeks.
