Identified
We've encountered a few instances of Docker jobs on the High Throughput system being unable to connect to the internet, with an error like "Could not resolve hostname github.com: Temporary failure in name resolution". We've identified the cause as being changes to our network firewall on particular machines. We are working to deploy a fix, but until we do the issue could become more widespread. If you encounter this issue, please email us at chtc@cs.wisc.edu with the specific Job IDs that encountered the error.
