Mixed

Results vary across ucsd.edu: of 13 URLs tested, 2 are blocked, 4 are disrupted some of the time, 6 load normally and 1 has no conclusive recent result. The Great Firewall blocks the connection outright. 321 tests have been run under this domain since 2012-05-11, the most recent on 2026-09-18.

Plain HTTP and HTTPS differ here: http://ucsd.edu is intermittent, https://ucsd.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.
