upenn.edu
Mixed
Results vary across upenn.edu: of 26 URLs tested, 7 are blocked, 2 are disrupted some of the time, 15 load normally and 2 have no conclusive recent result. The Great Firewall silently drops its packets so requests time out, breaks its TLS handshake and poisons its DNS. 566 tests have been run under this domain since 2013-02-12, the most recent on 2026-07-30.
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://upenn.edu is intermittent, https://upenn.edu 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 upenn.edu. 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.
