I don't run any more cron tasks other than those two mentioned earlier, log rotate and updated don't require any DNS lookups at all, and I don't run sysstat either. May be it is worthwhile getting up at 4 am in the morning and take a close look at the processes

Are you running any other utilities (like sysstat) that might give you more information. If the tasks that run at 4:am are intensive, you will see latency. If those tasks require DNS lookups, then it would explain the incrase in traffic. That's where I'd start looking.

I have only two tasks scheduled to run at 4 am in the morning and they are just log rotation and updated processes. They don't take even a minute to run.
