Download issue with base-mainnet-full-1767185314.tar.zst

Problem downloading base-mainnet-full-1767185314.tar.zst

I spent almost a month downloading snapshots of geth-full, but then one day the filename changed, and I had to download it again. I then spent almost another month re-fixing the base-mainnet-full-1767185314.tar.zst file for download, and then one day I got a 404 error. Which one should I download?
