Our SETI processing is unstuck.
They made a trivial change to their server status page (spaces were replaced with HTML nobreak spaces) and our parser no longer recognized the various required "server up" lines. Since the server was "down", the stats pulls were aborted to avoid pulling duplicate snapshots of old data.
The stats are designed to break if a page has unexpected values, so as to protect the data integrity going into the DB. It's not too hard to fix this way - cleaning bad data out of the DB and reprocessing is much more involved.
