Capacity issues in LHR region

New machine/volume creates in LHR regions are currently unavailable as there is no host capacity available. Any workloads currently running will continue to run; it is also still possible to update existing machines/volumes. Increasing `fly scale count` in LHR region is not possible. Blue-green deploys are also not possible at the moment, as well as deploys with `release_command`. We expect more capacity to become available in the coming weeks. For the time being, please choose a nearby region for new workloads, such as AMS (Amsterdam, Netherlands) or ARN (Stockholm, Sweden).
