static file (font) not downloading in SJC

I’m serving static files using this setup in my fly.toml:

[[statics]]
  guest_path = "/usr/src/app/static"
  url_prefix = "/static/"

my app is only deployed in a single VM to SJC. I previously was able to load the font fine. I made a small change to some other static assets and deployed just now. the font no longer finishes loading and instead hangs at exactly 2 KiB downloaded

$ curl -i https://sbds.fly.dev/static/data/NotoSansJP-Regular.otf > f
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

I noticed that I’m getting back fly-cache-status: HIT. I wonder if something went wrong with the caching of this asset and whether there’s a way to purge the cache

ok… 2 deploys later (which didn’t touch the static file), it appears to be fixed
