I ran tests of "apt clean; apt update; apt --download-only install --install-recommends tde-trinity; apt clean" twice each on three different VPSs, each in a different data center in a different US state. Prior to testing the VPSs had no X Windows and no TDE other than the keyring. Debian Buster. Speeds for the TDE portion of the downloads appeared to be roughly 10-35MBps (not bps).
With TDE r14.0.x I encountered no download errors.
I ran the six tests again, this time against TDE PSB. Again no download errors on TDE but I did get one download failure
one time from Debian:
E: Failed to fetch
http://ftp.us.debian.org/debian/pool/main/p/poppler-data/poppler-data_0. 4.9-2_all.deb
Undetermined Error [IP: 208.80.154.15 80] E: Some files failed to download
I conclude this is a network or apt problem rather than a TDE problem. It occurs more frequently for Felix so it might be a local router problem such as NAT table exhaustion.
I looked at: https://bugs.debian.org/cgi-bin/pkgreport.cgi?dist=stable;package=apt and there are HUNDREDS of open bugs. I couldn't find one that matched this but I don't see any point in trying to report an intermittent issue that might be a communication problem rather than an apt bug.
I don't think there's anything more that TDE can do. The workaround is to hit up-arrow then enter if download fails.

If this happens frequently for Felix, it may be a good idea to split the update so that first apt calls "apt upgrade --download-only", and only when everything is successfully downloaded does the package upgrade continue.
