Frequently Asked Questions
Should I Block special_archiver?
Rarely. special_archiver preserves snapshots of your pages through redesigns, migrations, and broken links. Blocking it prevents future captures but does not remove existing snapshots. To remove those, you must contact the archive directly. Almost none of the top websites we track currently have robots.txt rules for special_archiver.
Does special_archiver Follow Robots.txt Rules?
Yes. special_archiver is expected to follow robots.txt directives, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether special_archiver respects it.
Does special_archiver Access Private Content?
No. special_archiver archives only what an anonymous visitor can see. Anything public at crawl time may remain available in its archive long after you remove it from your site.
Why Is special_archiver Visiting My Website?
special_archiver is preserving your pages as part of a historical record. It returns periodically so the archive can capture how your content changes over time.
How Can I Tell if special_archiver Is Visiting My Website?
Agent Analytics tracks special_archiver visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user-agent string contains "special_archiver". Look for a page and its embedded assets being fetched again after a long interval. Because special_archiver does not publish a verification method, any client can claim its identity and a log match is only a clue.
