E.g. this job: https://travis-ci.org/apache/incubator-beam/jobs/176795223 or https://travis-ci.org/apache/incubator-beam/jobs/176795401 Search for "Connect to repository.apache.org:443" - log messages around these take up several minutes every time it happens, and it happens multiple times per build.
Is this a failure that Apache must take care of? Are we ourselves not caching Maven artifacts efficiently?
