2 * The parts of g1t the page lists, and how each is checked. Every address
3 * comes from the Worker's vars, so an installation of its own names its own
4 * hosts; a part whose address is empty is not part of that installation
5 * and is left off the page.
6 *
7 * Checks go over the public internet, as people reach g1t, so they measure
8 * what people see. Billing has no public address of its own, so it is the
9 * one part checked through a service binding, when there is one.
