Question about DNS resolution for discourse.orthanc-server.org

I’ve been having some trouble connecting to the new forum.

sscotti@Stephens-iMac ~ % ping discourse.orthanc-server.org
ping: cannot resolve discourse.orthanc-server.org: Unknown host

It seems to be intermittent and I would guess related to the DNS servers that I have configured with my ISP.

I might try changing them to:

8.8.8.8, 8.8.4.4 (Google)
1.1.1.1,1.0.0.1 (CloudFlare)

Just wondering if anyone has experienced a similar issue recently (seems like just the last week or so).
