Demos broken due to CORS errors in Firefox, Chrome

[inactivist]

Neither demo works for me in recent Chrome/Firefox releases - the tiles/features fail to render. The network panel shows various CORS errors for the S3-hosted tile data

Here's the Chrome network inspector taken from the basic demo:

Chrome Version 88.0.4324.150 
FireFox Version 85.0.1 (64-bit)
Ubuntu 18.04

Thanks for reporting. It looks like we have removed that s3 bucket entirely.
It's possible we'll fix that at some point, but it's not likely to be soon.

If you are really keen to test the demo, you can follow the instructions for getting your own sample tiles (or use tiles from another source that you already have access to).

Tiles (for Brighton, UK) were obtained free from openmaptiles.com for use, here, in this open source project. They are currently hosted within an AWS S3 bucket owned by LandInsight. After download they were upacked into .pbf using @mapbox/node-mbtiles (see script unpack_tiles.js here).
