Every verified onion address for Anubis Market. All resolve to the same market with the same account and balance. Try the first, and switch if it is slow.
Which of these you open changes one thing only, which is the route your traffic takes to get there. It does not change your balance, your open orders, which of the four coins a vendor will take, or what a deposit costs you. People switch addresses hoping to fix a payment problem or a slow deposit, and that has never worked, because the payment is happening on a blockchain that has no idea which onion you signed in through.
Your browser treats each of these as a separate site, so signing in on one leaves you signed out on the others. That matters more here than on a simpler market because an order paid in Ethereum and an order paid in Monero can be sitting at different confirmation stages at the same time, and switching mid session makes it look as though one of them vanished. It has not. Sign in again on the address you moved to and both are there.
The cost of switching is a fresh connection, which is tens of seconds, plus signing in again. Doing that once because an address is genuinely unresponsive is sensible. Doing it three times in an evening because pages feel slow costs you several minutes and gains nothing, since the slowness is almost always the circuit rather than the address.
Give a single attempt a full minute before judging it. A cold connection to a hidden service crosses roughly six relays with no caching anywhere, so tens of seconds of nothing is the normal state rather than a fault. If it still will not open, move to the next entry rather than reloading the same one, because a reload rebuilds the same failing path.
Open any other onion service you know. That single test separates a problem in your own client from a problem at the market, and it takes twenty seconds. If nothing onion works, restart Tor Browser completely. If other onions work and these do not, wait rather than hunting, because an outage consumes nothing: escrow keeps holding, orders keep their timers, and a balance does not evaporate because a storefront was quiet for an afternoon.
Not in the outage. In what people do during one. Searching for a replacement address is the single behaviour that turns an inconvenience into a lost account, because the results that surface at that moment are built for that moment. Keep these entries saved somewhere you can reach without a search engine and compare them against this page occasionally while everything works. How the clones operate covers why the timing is not a coincidence.
