PMTiles is great, but there's a risk hosting multi-gb files on metered hosting -- a client might not respect range requests and you open yourself up to a denial of wallet attack.

I can't really see doing it on S3, unless it's behind a lightweight tile server. I'd do it on hetzner or linode or one of the lower cost bandwidth providers.

(edit -- citybik.es is pretty cool, are you backing up to GBFS or a different set of data feeds? e.g. https://github.com/MobilityData/gbfs/blob/master/systems.csv is a list of ~ 800 gbfs feeds, some dockless, some docked I've done a bit of work in this space, feel free to ping me)

To mitigate the "denial of wallet" attack on S3 there are a few options:

AWS Lambda: https://docs.protomaps.com/deploy/aws lightweight tile server: https://docs.protomaps.com/pmtiles/cli#serve

Will keep that in mind if I go that route.

GBFS is just one format of the many supported. This is where we keep all instance data https://github.com/eskerda/pybikes/tree/master/pybikes/data . This is the list of GBFS systems we have https://github.com/eskerda/pybikes/blob/master/pybikes/data/...
