30 minutes may be too low. Should we aim for 10?

I think this is a good change for the cases where we marked our primaries as down while we were offline, and now we are only dealing with confirmed guards. This change will make us go back to our primaries much faster.

That said, this change has performance implications when the top primary guards are legitimately down, since we will have to wait about 2 minutes for each primary guard connection to timeout every 10 minutes.

I currently think that this change is worth doing, but I would need to test this branch more in real life situations to see if the performance penalty is too annoying.

Calling this implemented since the branch is merged, but we'll have to keep an eye on this.
