Low capacity in IAD

Update timeline

1. investigating Mar 27, 2026, 06:08 PM UTC

   We're currently investigating capacity issues in IAD that is preventing machine starts (machine creates are currently unaffected). This may result in deploys failing to complete (even for apps outside of the IAD region). As a workaround, using legacy Fly builders explicitly located in another region (i.e., `FLY_REMOTE_BUILDER_REGION=lhr fly deploy --depot=false --recreate-builder`) may help in the meantime.

2. investigating Mar 27, 2026, 06:47 PM UTC

   We're continuing to evaluate our options for increasing short-term capacity in the IAD region.

3. identified Mar 27, 2026, 07:21 PM UTC

   We've brought some additional capacity online in IAD and are seeing improvements, and we're continuing to work on adding more and freeing up additional room.

4. monitoring Mar 27, 2026, 09:09 PM UTC

   With the additional capacity we've brought online, machine start failure rates in IAD have now recovered. We'll continue to monitor IAD capacity.

5. resolved Mar 27, 2026, 09:51 PM UTC

   This incident has been resolved.
