Gregory's ServerFor example: there are implementations that do not conform to what the standard says is a MUST, but it's unlikely that will cause any interoperability issues.
Often they have good reasons for doing what they do, such as reporting "504 Gateway Timeout" -- a case the WebFinger standard does not consider.
How do we report that? So that's why you see the 4x4 matrix at the top of the report and the different shades of red.

Note: our categorization is experimental and you may disagree with it. We would love to hear suggestions on how to do better.
Of course, this is new code, and our tests may have bugs, too. To discuss, join us on Matrix and/or file issues.
