DKIM DNS failure but it can be resolved on the Internet

The DNS section, it can resolve all my DNS record except the DKIM TXT "s1._domainkey.eko.ws"
However, I can resolve it from all major public DNS server. e.g. https://mxtoolbox.com/SuperTool.aspx?action=dkim%3aeko.ws%3as1&run=toolpage#

I have the same issue but for reverse DNS - my rDNS is fine by any number of resolvers I've tried, all around the world but aboutmyemail reports a failure.

Reverse DNS for v6 addresses fails in some cases. Known bug.

SERVFAIL results typically mean a timeout from the local recursive resolver. It's hard to diagnose exactly what causes that unless you catch it live.

@wttw I did another test and got full green, all good. But knowing that this can randomly fail, it would be good if there was a "try again" button for this sort of failure - saves time and resources re-running the whole thing? Or failing that a note saying "Fail: this could be a false negative"?

[wttw]

Definitely. Surfacing DNS errors in the main report (rather than just on the DNS page) is on the TODO list for v2.

@wttw Great! And a massive thanks for this really helpful tool.
