AbstractDefines the correct posture during a service outage, identifies the behaviour that converts an inconvenience into a loss, and states the standing measures that make an outage inconsequential.
1. Posture
An outage costs patience. It does not cost money. Every documented loss connected to an outage comes from the reaction to it rather than the outage itself, which makes doing nothing the strongest available response in most cases.
2. Permitted actions
Rebuild the circuit and retry
Try another address from a set held before the outage began
Wait and retry later
Check whether other onion services are reachable, to classify the failure
3. Prohibited actions
Searching for a replacement address, which is the origin of most credential losses
Accepting an address from a message, comment or announcement that appeared during the outage
Entering credentials on any page that has not passed the login screen verification
Sending funds to any address published as an emergency alternative
4. Standing measures
Two measures make an outage inconsequential in advance. Hold a verified address set before you need one, so a failure produces an alternative rather than a search. And hold no balance on the market beyond the current order, so that even a permanent outage costs you nothing but access.
5. Distinguishing a permanent ending
A market ending is preceded by a recognisable pattern rather than by silence alone. Withdrawals slowing while deposits continue, support going quiet over weeks, established vendors leaving together, signed communication stopping while the site remains up. None of that is inferable from an address being unreachable for a day, and the standing measures above make the distinction unnecessary for your own exposure.
Required check. Open in Tor Browser only. Before entering anything, compare the onion printed on the login screen against your browser address bar. A mismatch means the page is a copy and the tab should be closed. See NM-004.
Specifies the account creation requirements that make a credential leak survivable, and identifies the one decision in the process that cannot be corrected later.
Specifies what to read on a vendor profile and in what order, distinguishes the fields carrying information from those that do not, and defines a first order policy.
