## PrivateBin public instance network

- `storage/privatebin-public-instance-network` | fails-quota | evidence documented | binding per-object-cap | category anonymous-dump
- identity a placeholder: card and phone unknown | verified 2026-11-03T15:03:57.980Z (live) | stale on 2026-12-04
- url https://privatebin.info/directory/
- free tier: 10 Megabytes (sizelimit = 10485760 bytes) per document or comment by default, set by each instance's operator; file upload is off by default (fileupload = false). | unit: unlimited | metered on: unstated | read on: 2026-10-21 | source: [1]
- per-object cap: 10 Megabytes per document or comment by default (sizelimit = 10485760 bytes); each instance's operator may change it. | bytes: 10485760 | source: [1] | note: not stated
- retention: Expiry is chosen per paste from options set by the instance operator: 5min (300 s), 10min, 1hour, 1day, 1week, 1month (30 days), 1year, and never (0, no expiry). | source: [1] | note: not stated
- egress: free, direct from each instance; most are Cloudflare-proxied (the directory lists CSP/Observatory ratings and uptime). | metered: no
- identity: anonymous
- interface: rest
- limits:
  - per-object-cap (binding): 10485760 bytes per document or comment by default (sizelimit) [1]
- limits note: 10 MB per paste by default (per-instance override); file upload is disabled by default (fileupload = false) and about half the directory shows no file-upload support; burn-after-reading and expiry are server-configurable.
- binding note: each document or comment is capped at 10485760 bytes by default; there is no per-account quota because there are no accounts to meter, and each instance sets its own cap
- interface detail: rest
- tooling: Encrypted JSON POST to the instance root with X-Requested-With: JSONHttpRequest; official JS client plus community CLIs. github.com/PrivateBin/PrivateBin (8690 stars). Instances are independently operated.
- composes with: N instances x 10 MB, and each instance is a separate operator with separate rate policy — so this is the one pastebin class where horizontal sharding across operators is native. Still only ~50 instances, so the aggregate is single-digit GB per round.
- reliability: Instances are volunteer-run with visible uptime as low as 47-49% in the directory, so shard redundancy is mandatory. Content is client-side encrypted, so the operator cannot dedupe or scan — and cannot recover your key either.
- notes: 10 Megabytes (sizelimit = 10485760 bytes) per document or comment by default, set by each instance's operator.
- evidence note: vendor pages captured 2026-11-03: https://raw.githubusercontent.com/PrivateBin/PrivateBin/master/cfg/conf.sample.php, https://privatebin.info/directory/; every field that decides the verdict cites one of these captures
- extras:
  - dead_end.failure_class: quota
  - dead_end.why: 10 MB per document by default (sizelimit = 10000000 in upstream conf.sample.php); ~30+ listed public instances, some with file upload enabled. No account, no quota.
  - dead_end.first_recorded: 2026-10-21
