Larder Marketplace Shows Our Stock Frozen Since 08:08

The Larder delivery marketplace has accepted no stock feed from Greengage.

Briefing

Greengage sends stock levels for 212 stores to the Larder delivery marketplace every five minutes from a cron job, which Dev moved to a new feeds host at 08:10 this morning.

Larder's partner team says the last feed they accepted arrived at 08:08, the minute Dev tested the export by hand, yet export.log records a clean start and finish every five minutes.

Customers are ordering items that have sold out.

Dev thinks Larder's ingest is dropping scheduled uploads; Sam suspects the new cron.d entry itself.

The fix is yours to find: hints, the recovery checks and the debrief unlock inside the incident.
