for those of us who are unable to use graphite because of the outage (it's currently 2pm on a wednesday in sydney, australia), here's how you can get around

gt sync

not working because it's unavailable

gt checkout main
git pull origin main
gt checkout <your-branch>
gt restack

and assuming your stack doesn't need any new PRs created or any parents changed, you can just do this to push all your branches instead of

gt submit --stack

# to see all PR branches in your stack:
gt ls --stack
git push --force-with-lease origin <branch1> <branch2> <branch3...>
