Slow image push times

Hi,
I have noticed in the last couple of days that pushing images to the Balena image registry is taking a very long time. I have 8 services in my Balena release, one is large (~9.5GB). Before Feb 1st, pushing the images to the registry was taking ~10 minutes. After Feb 1 it is taking ~1.5 hours. I am just wondering if something has changed recently?

I am running the balena deploy command from the balena-cli to build and push images. Most images are built and pushed to AWS ECR first, not build as a part of the balena deploy command.

my docker compose file looks like this:

version: "2"

services:
  service_1:
    image: aws-ecr.com/engine:service_1-v1
    network_mode: host
    volumes:
      - shared-data:/shared
      - service_1_data:/data
    privileged: true
    labels:
      io.balena.features.dbus: "1"
      io.balena.features.supervisor-api: "1"
      io.balena.features.balena-api: "1"

  service_2:
    build:
      context: service_2
      args:
        - BASE=aws-ecr.com/engine:service_2-prod-v1
    volumes:
      - service_2-data:/data
    network_mode: host
    privileged: true

  service_3:
    image: aws-ecr.com/engine:service_3-v1
    network_mode: host
    privileged: true
    labels:
      io.balena.features.dbus: "1"

  service_4:
    image: aws-ecr.com/engine:service_4-v1
    network_mode: host
    restart: "no"
    
  service_5:
    image: aws-ecr.com/engine:service_5-v1
    network_mode: host

  service_6:
    image: aws-ecr.com/engine:service_6-v1
    network_mode: host
    privileged: true
    labels:
      io.balena.features.supervisor-api: "1"
      io.balena.features.dbus: "1"

  service_7:
    image: aws-ecr.com/engine:service_7-v1
    network_mode: host
    privileged: true
    restart: "no"
    pid: "host"
    labels:
      io.balena.features.dbus: "1"
      io.balena.features.supervisor-api: "1"
      
  service_8:
    image: aws-ecr.com/engine:service_8-v1
    privileged: true
    pid: host
    network_mode: host
    volumes:
      - service_8-data:/data
    tmpfs:
      - /tmp-logs
    labels:
      io.balena.features.dbus: "1"
      io.balena.features.supervisor-api: "1"
      io.balena.features.balena-socket: "1"
      io.balena.features.journal-logs: "1"

volumes:
  shared-data:
  service_1_data:
  service_2-data:
  service_8-data:

Thanks for any help.

Just an update, I have changed our CI scripts to use balena push instead of balena deploy and wow, it is a lot faster (like 5 minutes vs the 1.5 hours)
