Several addresses at once, and what that means for you.
People expect a market to have an address the way a shop has a street. Hidden services do not work like that, and the difference is deliberate rather than sloppy.
A service reachable at exactly one address stops being reachable the moment somebody points a flood at it, and flooding one is cheap. Publishing several at once means the pressure has to be spread across all of them to have any effect. For you the practical benefit is smaller and more useful: when one is slow, another usually is not.
Account, password, balance, open orders and message history sit behind all of them equally. Switching costs nothing beyond a fresh connection. If an order looks missing after a switch, you are almost certainly signed out rather than looking at different data.
An address that has absorbed sustained abuse is worth replacing, and operators also rotate on a schedule so no single address becomes the one everybody depends on. That is routine maintenance rather than a warning sign, and it is why a bookmark pointing at one raw address eventually stops working.
Save all of them somewhere you can reach without a search engine. Nearly every phishing story starts the same way: a familiar address goes quiet, somebody goes looking, and the first plausible result wins. Having the list already in front of you means that moment never arrives.
Comparing your saved addresses against a published set takes seconds and is much safer done calmly than during an outage. Doing it once a month is enough.
