Jenkins uptime
Measured from multiple regions every 6 hours. Percentages count only checks that returned an availability answer — 8 days measured so far. A dash means that window does not yet hold enough measured days to publish a figure.

Each region runs its own request from a different part of the world. A service can be up for one continent and down for another, which is usually the first sign of a routing or CDN problem.
What Jenkins does
Jenkins is self-hosted build automation, so the software runs on your own servers and cannot go down as a service. What can go down is the project's shared infrastructure: the update centre serving plugin metadata, the mirrors distributing releases, and the plugin site. This page measures that shared infrastructure, not your own build server.
What an outage looks like
Plugin installation and upgrade fail inside an otherwise healthy Jenkins, with the update centre reporting no available plugins or timing out. Fresh installations cannot download packages through the mirror redirector. Pipelines that fetch a plugin or a tool during the build break, while pipelines using only what is already installed run normally.
What to do about it
Confirm which side is failing before restarting anything. status.jenkins.io lists updates.jenkins.io, plugins.jenkins.io, get.jenkins.io, and pkg.jenkins.io separately from the main website, so the component matching your error names the fault. A controller that builds fine but cannot fetch plugins is hitting project infrastructure, where waiting beats reinstalling.
Is it down for everyone, or just you?
If this page says Jenkins is up but it is not loading for you, the problem is between you and them. Run a check against any URL from all 18 regions to find out where it breaks.

How we measure this
- We request Jenkins's public endpoint every 6 hours from Fly.io regions across six continents — 8 of them answered the most recent check.
- A region counts as down only when it gets no usable HTTP response. A
403or429means the origin answered and refused us, which we report as blocked, never as an outage. - A single failing region is treated as probe noise. We only change the verdict when two consecutive cycles agree.
- Response times average only the regions that actually served the page, so a timeout never inflates the number.
- Where Jenkins publishes an official status feed we read it too. An all-clear from the vendor can soften an unconfirmed degradation; a vendor-declared outage only worsens our verdict when our own checks corroborate it.
