SERVFAIL for thec.ppr.tn.gov and pfis.isg.tn.gov
Checking https://cachecheck.opendns.com/ for thec.ppr.tn.gov and pfis.isg.tn.gov yields a near complete SERVFAIL. We use Umbrella in our environment and are getting intermittent failures in accessing this site. The site succeeds with 184.108.40.206 or 220.127.116.11. Using nsookups with our default Umbrella/OpenDNS usually fails, but occasionally succeeds in finding the IP.
According to the final post on https://support.opendns.com/hc/en-us/community/posts/360071604872-IP-address-not-resolving-using-opendns- these SERVFAIL issues can only be resolved by staff.
