Mixed
Results vary across mapbox.com: of 21 URLs tested, 1 is blocked, 9 are disrupted some of the time and 11 load normally. The Great Firewall blocks the connection outright and silently drops its packets so requests time out. 577 tests have been run under this domain since 2014-09-26, the most recent on 2026-07-27.
The two are filtered by different means — an unencrypted request by the address and keywords it carries in the clear, an encrypted one by the server name in its TLS handshake — so one working while the other does not is normal.

About mapbox.com and the Great Firewall
Results vary across mapbox.com: of 21 URLs tested, 1 is blocked, 9 are disrupted some of the time and 11 load normally. The Great Firewall blocks the connection outright and silently drops its packets so requests time out. 577 tests have been run under this domain since 2014-09-26, the most recent on 2026-07-27.
Plain HTTP and HTTPS differ here: http://mapbox.com is intermittent, https://mapbox.com is not blocked. The two are filtered by different means — an unencrypted request by the address and keywords it carries in the clear, an encrypted one by the server name in its TLS handshake — so one working while the other does not is normal.
A VPN or another circumvention tool routes the request outside mainland China, past the filtering that blocks mapbox.com. 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.
