vercal.app
Mixed
Results vary across vercal.app: of 2 URLs tested, 1 is blocked and 1 is disrupted some of the time. The Great Firewall silently drops its packets so requests time out. 16 tests have been run under this domain since 2023-11-04, the most recent on 2026-04-16.
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.

Plain HTTP and HTTPS differ here: http://vercal.app is intermittent, https://vercal.app is 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 vercal.app. 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.
