Ubuntu infrastructure has been down for more than a day

Canonical's Ubuntu infrastructure suffered an outage lasting more than a day that disrupted official communication channels (bug tracker, mailing lists, status pages) just as a critical privilege‑escalation vulnerability that can yield root was being handled. The outage hampered coordinated disclosure and patching, increasing short‑term risk for Ubuntu users and admins until Canonical can fully restore services and publish fixes. Monitor Canonical advisories, apply published security updates immediately, and verify integrity of update channels once services return.
