About u.to and the Great Firewall

Is u.to blocked in mainland China?

Results vary across u.to: of 45 URLs tested, 10 are blocked, 6 are disrupted some of the time, 2 load normally and 27 have no conclusive recent result. The site itself, http://u.to, loads normally. The Great Firewall resets the connection, drops the connection and blocks the connection outright. 1,373 tests have been run under this domain since 2015-08-25, the most recent on 2026-07-29.

How can I reach u.to from mainland China?

A VPN or another circumvention tool routes the request outside mainland China, past the filtering that blocks u.to. GreatFire runs GreatFire VPN; the Analyzer also tests the domains of many VPN and proxy providers, so you can check whether one is reachable before relying on it.
