the ci.rs485.network link appears to be an invalid page when [linked from github readme and the rs485.network page]. Based on the inclusion of a travis.yml it seems like you may have migrated from jenkins to travis ci 👍 (in part or whole). any visibility?

Nope, the travis.yml has been there for a while, Jenkins should still be a thing. I'm guessing it's just broken right now.

Thanks for reporting. It's back now.
