Pull Requests in some feedstocks are not triggering Azure build jobs. This has been observed on both staged-recipes and individual feedstocks since at least 27-Oct 5:43 AM GMT. Restarting CI (close-open) does not resolve the issue. Travis CI jobs do appear to get triggered. Some feedstocks additionally trigger an (unusual) Appveyor job that fails.

Maintainers are reminded to double-check that "passing" checks on PRs include build jobs before considering merging.

It is hypothesized that this is related to an Azure wide issue. Please see https://status.dev.azure.com/_event/559260722.
