Share of new sites using Cloudflare STUN
Each dot is one launch day. Line is the 7-day rolling average. Chart starts at first detection.
The shaded area was measured against a different set of sites, so the line can step there without Cloudflare STUN itself changing.
Coverage details
Amber: 8 July to 10 September 2026, before we improved our infrastructure to index new sites much sooner, often on the day they go live. Sites found that early often haven't finished setting up, so anything usually added after launch reads lower from 10 September. We record each site as it was when we found it.
The share is a proportion of whatever we were tracking at the time. For a single continuous measure, switch to launch platforms.
