How much bandwidth does your DNS servers use?
Currently we have two DNS-only servers handling all requests.
At this point we have moved ~130 cPanel accounts into this redundant system.
It looks like our dns1 server is constantly using 1-1.5MB/s serving these requests. Estimated bandwidth consumption per day is about 11.6GB in and 3.0GB out.
When we were building this kind of system, I asked a lot of estimates from different service providers and here at WHT. Usually people told that dns server usually use only few gigs per month. How can so many people give me such a bad estimate on this?
I recall that only ev1 suggested a 2000GB server for this job, and looked like they were right.
I wonder what will this bandwidth consumption be when we get all our clients into this system.. .. ~ 1000 client accounts and increasing all the time.
