The vendor points at indexers as the amplifier: 'Many Indexers maintain references to articles long after they've been removed from Usenet servers', so the NZB can be valid and the articles still gone.
Bindingnone Unlimited bytes; the first failure is a per-article 430/423 whose frequency is set by the indexer's freshness and the spool's retention.
Identitycard Paid account with email and card. No identity document described.
EgressUnmetered on an unlimited plan; article availability binds before bytes.
free allowance: none
Per-object capNot published; the unit is the article.
Retention'UsenetServer offers one of the highest article retention times available'; no day count on the page read.
Interfacenntp NNTP reader, TLS; standard article commands.

Composes withThe clearest documented split between the two article codes: 423 means the group is there and the article is not, 430 means the article is unavailable while the group remains readable, which is what a script can branch on.
ReliabilityAn indexer can point at articles the spool no longer holds; each such article is a per-file failure and only PAR2 or a second provider recovers it.
NotesThe vendor gives a number for none of them; the useful part of this page is the 423/430 split, which lets a client distinguish a missing group from a missing article. A vendor KB article says article access is unrestricted and uncapped; that is the only statement about volume on the site.
Evidence notedocumented The 423/430 distinction and the indexer behaviour are the vendor's own. No removal-by-notice cause is named on this page, which differs from Newshosting's page in the same group.
