Essential: three documented hostnames, one backend. Start with Link 001; fail over 002 → 003. Re-verify every address against a PGP-signed announcement before login.
Link 001 — Primary

If Link 001 does not connect within 60 seconds, switch to 002; then 003. Wait 5–10 minutes between attempts, request a New Identity for a fresh circuit, and avoid rapid retries that trigger rate limits. If all three stay down, wait for a PGP-signed rotation announcement — never trust new hostnames from DMs or search ads.
Verification reminder
Copy — never retype. Match all 56 characters. Close on install prompts or deposit-before-content. Full protocol: /mirror/ methodology. Desk independence and disclaimer: /legal/.
