perfSONAR User Q&A and Other Discussion

["Andrew Lake" <>]

Hi,

On the UKNOWN status issue, you may want to verify that DNS and your network connectivity work.  Specifically you need to be able to reach http://ps1.es.net:8096/lookup/activehosts.json and one of the URLs listed there.

Thanks,

Andy
