Free tier	8 GiB of disk per PPA - current official reference: 'Disk space \| 8 GiB; larger quotas considered on request at https://answers.launchpad.net/launchpad'. (Historical: PPAs were raised to a 2 GiB minimum in 2010 per the Launchpad blog; the 8 GiB figure is the current documented one.) 'PPAs per owner: One or more per user or team; each has its own URL.' unit GiB; metered on stored-bytes
Price	none stated
Per-object cap	not stated
Retention	This is the binding constraint - you cannot push an arbitrary tarball; everything must be a signed source package (.dsc + orig.tar.gz + debian.tar.gz), so a 4 GB blob becomes one 4 GB .orig.tar.gz (allowed, but must be a valid Debian source package). retention: indefinite - 'A published package remains available until ..
Egress	Free: 'Data transfer \| No fixed cap; unusual volumes may trigger contact from Launchpad.' Served from ppa.launchpadcontent.net with no billing.
Identity	email (placeholder) not published
Limits	per-ip-shaping 70 KB/s source per-object-cap: 'Uploadable artefacts \| Source packages only; pre-built binary uploads are rejected' and 'Package formats \| .deb only'. This is the binding constraint - you cannot push an arbitrary tarball; everything must be a signed source package (.dsc + orig.tar.gz + debian.tar.gz), so a 4 GB blob becomes one 4 GB .orig.tar.gz (allowed, but must be a valid Debian source package). retention: indefinite - 'A published package remains available until ... the owner removes it, or a later upload supersedes it.' request-rate: not documented; download is plain HTTP. Measured single-stream throughput on a real PPA .deb was only ~70 KB/s.
Binding	per-ip-shaping one stream is shaped, and a user's throughput is the shaped rate times the number of streams
Interface	rest, ftp, rsync, rclone rest
Tooling	`dput`/`dput-ng` (rsync+ftp upload to ppa.launchpad.net), `apt`/`deb-src` for consumption, Launchpad REST API + `launchpadlib`. No rclone backend.
Composes with	N PPAs per owner ('one or more per user or team') x 8 GiB each x unlimited free Launchpad accounts and teams. A team can own multiple PPAs, so 8 GiB x N. For 20 TiB archive that is ~2,560 PPAs - achievable across accounts/teams but operationally heavy, and each is a separate signing key/deb repository.
Reliability	The read path works and supports ranges (verified 206 on a 1 MB range of a real .deb) but single-connection speed was poor (~70,666 B/s over 15 s). Batch/sharded fetch needed. Upload requires GPG-signed source packages - no arbitrary blob PUT. help.launchpad.net and blog.launchpad.net returned 503 to the reader all session (used archive captures instead), so the live help site is unreliable to fetch programmatically.
Notes	8 GiB of disk per PPA - current official reference: 'Disk space \| 8 GiB; larger quotas considered on request at https://answers.launchpad.net/launchpad'. (Historical: PPAs were raised to a 2 GiB minimum in 2010 per the Launchpad blog; the 8 GiB figure is the current documented one.) 'PPAs per owner: One or more per user or team; each has its own URL.'

Free tier	1 GiB PER FILE in the project file release area - a separate, much smaller surface than the PPA. The manual says: 'Each individual file must be no more than 1 GiB and you must be the: project maintainer / project driver / or the series release manager.' There is no published total-per-project cap; the unit of accounting is the individual release file. (The 8 GiB figure widely quoted for Launchpad is the PPA disk quota, verified in round 2 - it does not govern file releases.) unit GiB; metered on unstated
Price	none stated
Per-object cap	1 GiB PER FILE (1073741824 bytes)
Retention	not stated
Egress	Free, no billing. Files are served from launchpadlibrarian.net behind a 303 redirect. No published transfer cap; round 2 measured ~70 KB/s single-stream on a PPA .deb, which is a throughput problem rather than a quota one.
Identity	institution derived from the record's prose, not from an identity field, and no signup was executed: padlibrarian.net -> 200, 419,427 bytes). Write path is web/API only with no bulk transport, so it is a worse fit than a forge with SFTP. The docs being stale-and-unrevised is a real
Limits	per-object-cap 1 GiB PER FILE source per-object-cap: 1 GiB hard per release file. Also content-typed: files must fall into 'code release tarball / installer files / README or other documentation / changelog file / release notes' - arbitrary blobs are off-spec. retention: indefinite per release. request-rate: not documented for the file area; the docs page itself is flagged 'migrated from help.launchpad.net as is, and has not yet been revised'.
Binding	per-object-cap the per-object cap sets the shard size and therefore the object count; it bounds the total more tightly than any headline quota
Interface	rest, sftp, rsync rest
Tooling	Web upload per release ('Add download file') is the documented path - no SFTP/rsync equivalent to Savannah or SourceForge for the release area. Automation goes through the Launchpad web service API: `launchpadlib` (Python), the `+download` URL shape, and hardware-bound API tokens. Consumer side is plain HTTPS GET with an MD5 and optional GPG signature per file.
Composes with	unlimited projects x unlimited series x unlimited releases x 1 GiB per file. At 1 GiB granularity 500 GB is 500 files - feasible but operationally noisy, and every upload is a web action unless scripted via launchpadlib. Distinct from the PPA path (8 GiB/PPA, .deb-only, dput/rsync upload).
Reliability	Read path verified working end-to-end (303 -> launchpadlibrarian.net -> 200, 419,427 bytes). Write path is web/API only with no bulk transport, so it is a worse fit than a forge with SFTP. The docs being stale-and-unrevised is a real risk: the 1 GiB number is from a migrated page, not a maintained limits table.

The manual says: 'Each individual file must be no more than 1 GiB and you must be the: project maintainer / project driver / or the series release manager.'
