Re: [iu-lead-dev] lead.unidata.ucar.edu:8080 LEAD thredds server unresponsive



Hi Felix,

Interesting. A restart of the tomcat server has seemed to fix the problem, although I am noticing the restarted server does seem very busy. I'll keep looking.

Best regards,

Hi Brian and Mike, THREDDS team,

It looks like Unidata LEAD THREDDS server at http://lead.unidata.ucar.edu:8080/thredds/lead/leadcatalog.html is not responding again.

In addition to being unable to access the web frontend, our indexing tool is not able to crosswalk data products
Can you please check into it?
Thanks,
Felix
