5 of the 6 URLs we have a verdict for under ubddns.org are blocked in mainland China; 1 are not. The site itself, http://ubddns.org, is blocked.

A VPN or another circumvention tool routes the request outside mainland China, past the filtering that blocks ubddns.org. 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.

Each URL's status is its verdict over the last 90 days, the same one its own page headlines.
