SHIFT download page and file server return 502; download.py fails to download dataset

[areslp]

Hi maintainers,

I tried to download the SHIFT dataset following the DevKit instructions. The README suggests using the provided download.py script or manually downloading via the official download page or file server. Unfortunately, neither of those endpoints is currently reachable from my environment, and the script cannot proceed.

What I did:

1. According to the README, the manual download links are:

   • https://www.vis.xyz/shift/download/
   • https://dl.cv.ethz.ch/shift/

2. I tested these URLs directly with curl:

   # test the official download page
   curl -I https://www.vis.xyz/shift/download/
   # test the file server
   curl -I https://dl.cv.ethz.ch/shift/

   Both commands returned HTTP/1.1 502 Bad Gateway on every attempt, which means the endpoints are inaccessible (my network goes through a proxy and receives a 502 error).

3. Because these endpoints are unreachable, running the recommended script also fails. The script attempts to access the download page and cannot proceed, so no data are downloaded.

Expected Behavior

• The download page and file server should be reachable so that download.py can fetch the selected subsets.
• If there is maintenance on the official URL, the script could fall back to another endpoint.

Actual Behavior

• Accessing https://www.vis.xyz/shift/download/ and https://dl.cv.ethz.ch/shift/ with curl returns HTTP/1.1 502 Bad Gateway from the proxy.
• Consequently, download.py fails to download data.

Environment

• OS: macOS 14
• Python version: Python 3.10

Request / Suggestions
Could you please check if the download endpoints are temporarily down? If the vis.xyz and dl.cv.ethz.ch domains are no longer hosting the data, would it be possible to provide an updated mirror or adjust download.py to use another server?

Thanks!
