Attention, Ubuntu 14.04 and 16.04 Machine image users.
We are commencing the third brownout session on May 19 2022, as part of our efforts to deprecate the Ubuntu 14.04 and 16.04 Machine images by May 31, 2022.

For this third brownout session, the deprecated images will be unavailable for 3-hour periods as follow:

- UTC 00:00 — 03:00

- UTC 08:00 — 11:00

- UTC 16:00 — 19:00

Please refer to this page if you would like to understand the schedule in your time zone.

During this third brownout, jobs declaring machine: true will not fail.
Instead, these jobs will be using the new Ubuntu 22.04 Machine image (ubuntu-2204:2022.04.1 ) as a default.

However, if your jobs are failing with the following error `failed to create host: Image is not supported`, please migrate to a supported version of our Ubuntu Machine images.

You can find our migration guides below:

In addition, please refer to our blog posts to find out more about this deprecation and brownouts:
