We're looking into some errors contacting our Redis instances, and the app is down.
App & autoscaling are up and running.

Autoscaling is up and running.
We're seeing an increase in errors from Heroku when trying to talk to their API and trigger autoscaling, started around 12:05 UTC.

Looks like Heroku's API started working just as I was posting the last update. Everything looking good as of now... Continuing to monitor.
We've received some reports of upscaling not triggering, and are investigating.
Upscaling is working as expected. We'll be writing up a full report of what happened and what we're doing about it, but here's a summary: At 2025-08-07 00:25:00 UTC we ingested some unexpected queue metrics for a far-future date. It looks like a customer triggered this from their laptop. Our upscale logic looks at the most recent metrics bucket as a boundary, so this data broke our upscaling. We have many automated checks in place, but none caught this, and unfortunately it happened overnight for us, so we weren't aware of the issue until this morning around 2025-08-07 12:00:00 UTC. We identified the bad data and deleted it at 2025-08-07 12:36:00 UTC. Upscaling immediately started working as expected. We're implementing a permanent fix now, as well as automated checks so that we're alerted immediately in the future. Check our blog later today for a more thorough write-up.
