I should provide a couple more details of what I've seen:

  - The portsnap fetch downloads the 49MB .tgz, and it extracts
    properly.  This file is not corrupted (passes gzip checksum).

  - In the portsnap/snap directory, many of the <checksum>.gz
    files are correct, but many (looks like 1/4?) of them are
    truncated somehow.  They are gzip files, but they are corrupted.
