ubuntu archive is shrinking significantly...

[Carlos Carvalho]

The size of the archive distribution reduced by about 60GB in the last
week. Also, our sync script aborted this night because it exceeded the
limit of 50,000 deleted files (we set this threshold as a safeguard).
The run of this morning deleted a further 10,000...

These big reductions, combined with the date at syowa being completely
wrong (now corrected), make me concerned about the health of the
archive. Is everything all right?
