(3) If you look at the sample grid at

it is 30x30 but not quite symmetrical:

- albq-owamp.es.net appears on the left but not the top
- sdsc-owamp.es.net appears on the top but not the left

Is this actually a disjoint mesh rather than a full mesh? If so, why would it be configured that way?

(4) Looking at the same example I also note that some tests are visible at the intersection (A,B) but not (B,A). In the second direction the square is white

I think I can answer that part now, it's clearer looking at another one:

With a disjoint mesh, you can have tests configured between arbitrary pairs; no test configured = white.

I solved this, and in my opinion it's a UI design problem.

When you hover over a square, the whole square is highlighted; the implication is that the square is a single clickable button. However clicking on the top half of the square does something different to clicking on the bottom half of the square (two different results pages are opened).

I think that if it were to highlight the halves separately it would be much clearer what was happening.
