Hello 
Since last week we were having some issues with Travis. And after some debugging, we found that we have timeouts on the network. Please see the screenshot. I was able to download the file. It exists. But Travis couldn’t. Does anyone have the same issue?
Since some days I also see various network problems: sometimes git-clone operations time out or are very slow, sometimes it’s apt-get which is failing due to timeouts, sometimes other http downloads fail. Rerunning the jobs sometimes helps to fix the problem.
The jobs are running on arm64 architecture.
