Every record we hold is listed here, newest first. A record is never removed from this list, so a vendor named here stays named here whatever its verdict does afterwards.

At-Risk Vendors
All 3 of the 27 vendors we list in this category that carry one. A vendor is named here for as long as a demotion is in force against it: a one-off pricing event, recorded against a source we cite, whose date falls in the last 180 days — or a standing condition, also cited, such as a free tier withdrawn or a product retired, which does not expire with time. A demotion can lift with nothing about the vendor having changed, and that happens on the day the vendor's newest qualifying event passes 180 days.
All 12 of the 27 vendors we list in this category that qualify, not a selection of them. A vendor is named here for as long as no demotion is in force against it and we hold no change record for it dated in the last 90 days — any record, including ones the timeline above does not count. A vendor can join this section on a day we recorded nothing about it, when the later of those two clocks runs out: 90 days after its newest record, or the day the demotion against it lapses. It leaves on the day we file a new record, or the day we can no longer vouch for the terms we list.
