About these figures
- A domain is a name registered under a .za zone, such as uct.ac.za, with the sites under it, such as lib.uct.ac.za. Its status is the best of its sites': active, then unavailable, then blocked, then dead.
- Only links between .za sites in the census are counted; links from outside .za, social media and search engines are not observed.
- Links added by scripts after a page loads may be missed, and pages Palo has not crawled are not seen.
- As of the analysis on 3 November 2026, 20:30 SAST. The data is CC BY 4.0; credit “Palo, Dirišwago (palo.dirishwago.co.za)”.
