Hello dear users and contributors,

As described in https://www.jenkins.io/blog/2024/09/25/update-center-brownouts-4/, we are starting another 24 hour brownout on the Update Center.

We expect no incident this time as we added full HTTP-only support but we never know.

For the Jenkins Infra team,

Damien Duportal

Hi,

Our tests are failing today when installing various components, for example:       0.749 [id=71]  WARNING  o.e.jetty.server.HttpChannel#handleException: handleException /updates/hudson.tasks.Maven.MavenInstaller.json.html java.io.IOException: Server returned HTTP response code: 403 for URL: http://westeurope.cloudflare.jenkins.io/updates/hudson.tasks.Maven.MavenInstaller.json.html
404s can also be seen in all versions linked here https://westeurope.cloudflare.jenkins.io/download/plugins/gradle/index.html.

Thanks for the feedback!

We are working on this:
  • The HTTP/404 are links in the "index.html" page which are relative. We missed this as these request are not in the server-side access logs we replayed as it's only client-side. It's a consequence of the new system (which now redirects to the final URL) and we need to find a solution.
    • How much is it a blocker for you? Is it acceptable to have this behavior until tomorrow (time for us to finish the brownout)?
  • We are investigating the HTTP/403 errors you received. We can't find them in our access logs as it seems to be responded by Cloudflare: investigation in progress (we might g-have unknown limitations on Cloudflare). But the new system works as it redirects you to the closest mirror to your location.

We'll keep you informed, sorry for the inconvenience

Hi Alexis, could you retry? We've detected that a default WAF rule on Cloudflare was blocking a lot of requests (including yours) due to some HTTP headers. It's a default setting which we disabled given it won't serve us.

That should solve the HTTP/403 errors

Indeed, tests are fine now!

Regarding the 404s on the download links, they are not a blocker and can wait.

Thanks and good luck with the migration
