>FWIW we saw virtually no usage change on dialups or WAN here.

We saw a large increase in incoming traffic at 00:00 UTC (jumping from 
about 5Mbps to a peak of 108Mbs - as we're primarily doing hosting our 
incoming is usually very low compared to outgoing). We assume this was 
some form of DoS attack (although it did not saturate any of our 
infrastructure), which lasted for about 30 minutes then just stopped.

Other than that, we did not see any significant increase in traffic around 
00:00 - either UTC or USA time.

You can see graphs of our traffic over the period at:
