When Discord introduced temporary validity for asset links, they notified us months in advance.
Less than a month ago, they introduced new CDN servers sc0 thru sc7 with hashed links which give us only temporary access.
Traditionally, a hashed asset URL would remain valid permanently. That changed and now you can only cache a redirect URL for 14 days.
This picture was taken (by someone I know) on 2024-10-23. It leads to https://assetdelivery.roblox.com/v1/assetId/1818.
On 2024-11-12, I verified that the old CDN servers were still working with the following command line:
curl https://c2.rbxcdn.com/3531bd1e0747fccbf5df1aea7e3fc903
It worked and I downloaded the Crossroads map.
However, on 2024-11-19, I tried again and…
PS C:\Users\USERNAME> curl https://c2.rbxcdn.com/3531bd1e0747fccbf5df1aea7e3fc903

These links are now only valid for 14 days:

I also took this picture on 2024-11-19. I would’ve received a similar result on the 12th when reaching https://assetdelivery.roblox.com/v1/assetId/1818.
