There were quite a few regressions with vibe.d since 2.074.0 that went undetected (see e.g. https://github.com/dlang-tour/dlang-tour/pull/519#issuecomment-304724314).
However, I think this one is just a transient issue (it just adds a test after all).

Yeah. Unfortunately has the Jenkins a lot of transient / unrelated failures and there's no easy way (yet) around this.
I think Martin wanted to give more people access to the server and/or implement auto-restart of failed builds from time to time.

I just disabled the requirement for Jenkins to pass for the druntime repo (due to the instability it we also disabled it on the dmd and Phobos repo recently).
These PRs should get merged quite soon. One is already in.

In theory the versions are locked, so that (without transient issues) red means there's a regressions.
IIRC especially getting packages from the DUB server tends to have random failures "regularly".
So, as mentioned above there are still some stability issues that need to be fleshed out with our ecosystem / DUB / Jenkins.
AFAIK there's also an unaddressed regression that slipped through during the time Jenkins was broken and disabled for dmd/phobos:
https://issues.dlang.org/show_bug.cgi?id=17472
Obviously if Jenkins is stable enough, the plan is to enforce its passing state, s.t. no regressions can silently slip through.

The bot can already do this, it's just not deployed (yet) and instead of sending out mails,
for now (testing stage) it would just label such PRs, see for more information this PR:
