The one URL under t-systems.com we can reach a verdict on is blocked in mainland China. The Great Firewall silently drops its packets so requests time out. 26 tests have been run under this domain since 2017-05-19, the most recent on 2026-04-13.
A VPN or another circumvention tool routes the request outside mainland China, past the filtering that blocks t-systems.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.
