There were. The e1000 card kept complaining

e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang

under heavy load. Not sure whether that's a new problem,
or just now occurring due to increased load; notably,
the problems were much reduced over this weekend.

People reported that this may be due to bugs in the Linux
e1000 driver, but none of the suggested changes (most recent
driver, various module parameters) had any positive effect.

I have now moved PyPI to a different machine (the same
as www.python.org), and see whether I can get the network
card (or perhaps the cabling) replaced. www.python.org is
a quite larger machine, so it should be able to cope with
the extra load.
