We seem to have repeated network errors on a number of our builds recently.
Example is here: https://travis-ci.org/apache/airflow/jobs/646256516?utm_medium=notification&utm_source=email
It is just one example where we failed to reach two different apache backup servers (it’s highly unlikely to happen at the same time). We had also other - similarly looking errors with different network server - this indicates some problem with the underlying network infrastructure.

Another example here - with github, so it must be a network issue:
