It appears that that at least some jobs on Beta halted on 2020-06-18, when the old deployment-changeprop and deployment-cpjobqueue instances were shut down as a result of T255068.

I don't think this is merely a matter of a dashboard needing to be updated, because fetchGoogleCloudVisionAnnotations jobs are actually no longer running since then. (Some jobs do still seem to be running, as reflected on deployment-fluorine02:/srv/mw-log/JobExecutor.log; I don't know how some job types are being processed and not others.)
