Travis not posting status updates to github?

Hello.

This morning we’re seeing a number of Github PRs where a build is triggered on travis, but the status isn’t posted back to Github. Here’s two example PRs:

I don’t see anything on either the Github or Travis status pages. Is this a known issue?

EDIT: After triggering retries on one of the jobs a few times, eventually github got the status update, so I guess this is resolved.

The post says about travis-ci.com but this apparently affects the same kind of check at travis-ci.org, too.
