We began crawling the wider web on this date, so the cohort this share is measured against changes here. 10 September 2026: we improved our infrastructure to index new sites much sooner, often on the day they go live, so the cohort this share is measured against changes here. 5% 2% 0% Apr May Jun Jul Aug Sep Oct Weekly averages before this point, daily after.

The shaded areas were measured against a different set of sites, so the line can step there without Microsoft IIS itself changing.

Coverage details

Before the dashed line where the dots begin, the line is a weekly average. After it, the last 90 days are shown one day at a time.

Grey: before 8 July 2026, we only tracked launches from launch platforms. From that date we crawl the wider web as well.

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.

Country

Country likely for 6,527 of 23,172 sites (28.2%), all time.

How we know

Country comes from what each site says about itself, such as a company registration, legal terms or a phone number, not just its domain ending. Too few sites state their country plainly for the usual count, so this one also counts single signals: a country domain ending, a phone number (for North America, its area code), a location the site declares in its own page metadata, or a country-specific vendor stack and the page language where they agree and nothing contradicts them. Read these as likely rather than certain.
