Hello,
I've observed that our border routers are getting pinged a fair bit.
I measured on one router and saw:
5 per second, seems consistent throughout the day,
roughly 40 different sources every 15 seconds
I took a look at the varied sources and discovered that the sites
are well connected and those that resolve resolve to akamai names.
This isn't more than a nuisance for me, but I run a small net.
Should I conclude that an ISP with a population 10 times bigger
would have their border routers getting pinged at 10 times the
rate I see? If so, should we care, or just ignore it?
Thanks,
-mark
