Servers that left
The lists above are the registry as it stands. A server that is removed keeps its page here as a dated record of the disappearance, because that is the part nobody can reconstruct later.
Every server delisted since our first census - when each was first seen, last seen, and the verdict it carried when it went.
How this census works - denominator, tiers, and what each check does.
