A verdict here is not a fixed property of the vendor. A one-off pricing event demotes a vendor while its recorded date falls in the last 180 days and then lapses on its own, with nothing about the vendor having changed; a standing condition — a free tier withdrawn and not restored, a product retired — does not lapse with time. This one rests on a record discovered 2026-09-27 · effective date unknown, so it lapses on 2027-03-27 unless we record something new first.

Retracted — this record was our error (2026-09-10). Retracted 2026-09-10: the record's own summary reads "The free tier now has a limit of 200 messages/second instead of 50", which is an increase, and it is typed limits_reduced. svix.com/pricing/ states the Free plan at "200 messages / second" today, against the 50 msg/sec we hold. The 2026-09-09 limits_increased record on the same page carries the same reading with the correct type. Source ↗
