Reviewing CDash, we can confirm that yesterday extensions were built for both:

- Stable:
  - CDash: [https://slicer.cdash.org/index.php?project=SlicerStable&date=2025-02-02&filtercount=1&showfilters=1&field1=site&compare1=63&value1=metroplex](https://slicer.cdash.org/index.php?project=SlicerStable&date=2025-02-02&filtercount=1&showfilters=1&field1=site&compare1=63&value1=metroplex)
  - Extensions: [https://extensions.slicer.org/catalog/All/33216/linux](https://extensions.slicer.org/catalog/All/33216/linux)

- Preview (aka Nightly):
  - CDash: [https://slicer.cdash.org/index.php?project=SlicerPreview&date=2025-02-02&filtercount=1&showfilters=1&field1=site&compare1=63&value1=metroplex](https://slicer.cdash.org/index.php?project=SlicerPreview&date=2025-02-02&filtercount=1&showfilters=1&field1=site&compare1=63&value1=metroplex)
  - Extensions: [https://extensions.slicer.org/catalog/All/33455/linux](https://extensions.slicer.org/catalog/All/33455/linux)

That said, we can indeed see missing builds.

Notes:

- Following the failed builds reported between 01/27 and 01/29, we performed cleanup of orphan and unused docker images along with setting up daily restart of the system to ensure there are no lingering docker builds.
- We are still investigating the failures of 02/01 and 02/03.

> re: We are still investigating the build failures from 02/01 and 02/03.

Now that Slicer 5.8 has been released, we will proceed with backing up the relevant build trees in preparation for updating the underlying operating system and transitioning to a more recent Docker engine. Our goal is to minimize disruption while improving system reliability.

The current Docker engine version has been unstable and frequently encounters the following error:

```auto
2025/02/03 01:49:09 grpc: Server.processUnaryRPC failed to write status stream error: code = 4 desc = "context deadline exceeded"

```

To address this, we will schedule a system upgrade. A dedicated post will follow to coordinate the required downtime.
