Any other ops noticing a sharp increase in DNS traffic since late
yesterday or so?

I don't keep any logs, so I can't give a detailed report, but 'named'
CPU usage has climbed significantly along with UDP traffic on port 53.

I'm just trying to estimate if this is a trend or if this is a once-time
event of some sort. If it's a trend then I probably need to start
budgeting for some hardware upgrades at some point, my DNS is running
only on a single core, 32-bit 2GHz CPU @ 1.5 GB RAM. I've got plenty of
RAM, but 'named' since perhaps around midnight last night has the CPU
pegged at 45-55%.
