We are deeply sorry for the outage of our sudo-enabled Precise and Trusty builds this morning.
We’ve determined that an image cleanup process malfunctioned and deleted the stable build environment images. Due to various factors our only option at this point is roll forward with newer build environment images, for both Precise and Trusty.
We’re resuming builds with these new images, but these new images have not undergone thorough testing, so it is possible your builds will break.
If you see issues with your builds failing, please email firstname.lastname@example.org, our engineering staff is available to help with any issues you run into.
We’ll also continuing to investigate the exact cause of the issue and will be publishing a postmortem as we learn more.
