Each check runs from all locations at once. A location far from the site’s servers answers later; that says nothing about the site being slow.

Outage history

No confirmed outage on record. An outage is listed once Zotero could not be reached from at least two locations in two checks in a row.

Zotero is a free, easy-to-use tool to help you collect, organize, cite, and share research.

Visit zotero.orgTitle and description as published by the site.

We can reach it, but you cannot?
  • Reload the page without the cache: Ctrl + F5 on Windows, Cmd + Shift + R on a Mac.
  • Open the site in a private window. If it works there, clear the cookies and cache for zotero.org.
  • Try another network, such as mobile data. If that works, the problem is with your provider or router.
  • Switch to a public DNS resolver such as 1.1.1.1 or 8.8.8.8, then flush your DNS cache.
  • Turn off VPNs, proxies and ad blockers for a moment. Some sites refuse those connections.
