Recovery, rental proxies
4+ failed connects in 15 min: the sticky session is swapped, new exit IP, same credentials
at most once per 30 min per account, 10 per sweep
held back while over 30 % of accounts fail: that is an outage
still failing after 6 h: paused, proxy_unreachable
manual rotate: your own proxies only
Traffic
50 MB per rental bundle per month included
beyond that, $6 per GB from the wallet; top up data any time at $6/GB
your own proxies are not metered
bulk import: up to 100 proxies per request

Nothing is quarantined or retested on a timer. Worker start: offline leak check, proxy host ≠ server IP (else paused, ip_leak). Unreachable proxy: account retried at 30 min, doubling, 5 tries.
