What UpButler measured

There is no keyless endpoint of Courier that says anything useful, so UpButler does not probe it. To check your own Courier account, add a monitor with your key: it is yours alone and catches what a shared probe cannot.

Get alerted when Courier goes down

No account. One email when Courier reports an incident, one when it is over. You confirm the address first, and every email has a one-click unsubscribe.

Or follow the RSS feed. On UpButler? Add Courier as a dependency to route it to Slack, Teams or a webhook.

Status badge

Show Courier's current status in a README or an internal wiki. It updates by itself.

Tell your outage from Courier's

Declare that your project depends on Courier. When one of your monitors fails while Courier has an incident that began around the same time, UpButler tags your incident "likely upstream" with their incident linked, says so in the alert and the AI report, and tells your on-call agent not to change code.

npx upbutler init finds the dependency from your env var names and packages. The catalog, dependencies and upstream-aware incidents are on every plan, including Free.

Questions

Is Courier down right now?
No. As of 2026-10-10 07:16 UTC, Courier is up. This page reads the status again every 3 minutes.
Where does this status come from?
From Courier's own status page API at https://status.courier.com. UpButler reads it once for everyone (not once per visitor) every 3 minutes with conditional requests, and shows it unchanged: incident titles and component names are Courier's words.
Can I get an alert when Courier goes down?
Yes, without an account: enter your email on this page, confirm the link we send, and you get one email when Courier reports an incident and one when it is over. There is also an RSS feed at https://upbutler.com/status/courier/feed.rss. Teams on UpButler can route the same alert to Slack, Teams or a webhook.
How can my agent or app check Courier status?
Fetch https://upbutler.com/status/courier/status.agent.json: a small JSON document with a verdict (proceed, retry, fallback or pause) and retryAfterSec. No key is needed. The same answer is an MCP tool, upstream_status {"service":"courier"}, on https://upbutler.com/mcp/public.
How do I know whether an outage is mine or Courier's?
Add "courier" to the dependencies of your UpButler workspace. When one of your monitors fails while Courier has an incident that began around the same time, your incident is tagged "likely upstream" with their incident linked, and your on-call agent is told not to change code.

UpButler is not affiliated with Courier. Status and incident text belong to Courier and are read from their public status source; the probe result is UpButler's own measurement.
