Save Pages in the Wayback Machine - Internet Archive Help Center Robots
- Robots.txt: If a website owner used
robots.txt to block crawlers at the time of capture, the page was not saved. (As of 2017, the Archive stopped respecting future robots.txt exclusions for already-saved pages, but historical blocks remain).
- JavaScript & Databases: The machine saves static HTML. It cannot run complex server-side scripts (PHP, Python) or query live databases. Consequently, interactive sites (old search engines, forums that required login) are usually frozen placeholders.
- The "Not Available" Flag: If you see a calendar with no blue dots, the crawler tried to visit but was blocked by a server error (HTTP 403, 404, 500) or a network timeout.
- Delay: A page crawled today may take 6 to 12 months to appear in the public interface due to indexing and quality checks.
- Crawling: The archive uses web crawlers (bots) to navigate the web and download publicly available pages.
- Snapshots: When a page is archived, a "snapshot" is taken. A single URL might have thousands of snapshots spanning years or decades.
- User Contributions: In addition to automatic crawling, users can manually submit URLs to be archived instantly via a "Save Page Now" feature.
