PSA: There is something going on with OpenDNS

So I have been using OpenDNS as my DNS and just about 5 minutes ago, I could not open a single website on my firefox with the error: https://i.imgur.com/SU881Yg.png

Having figured this had something to do with firefox, I switched to Brave but got the same message. Then I opened certificate details - saw Open DNS's name in the issued to column - reverted back to default DNS in my router settings and voila! Everything came back to normal.

Any explanations or similar experiences?

    Can you provide some logs? i.g. dig output of sites you try to visit, using OpenDNS and your ISP's DNS. Do you get the expected results here: [1] (Note, some of the resolvers may time out)
