- Subject: [opennic-dns-operations] A month of T2 statistics
- Date: Sat, 3 Oct 2015 10:26:10 -0400
For those that are interested, below are the statistics of an OpenNIC T2 DNS server, collected over 30 days.
This server, located in Milan (IT), has been in continual use for nearly 3 years, so it is well-established with those who want to use an OpenNIC resolver.
This server is consuming 961MB of RAM, and 50% CPU utilization of a dual-CPU (Xeon E31270) system.
Note that this server is rate-limited at the insistence of my ISP (to limit participation in DDoS attacks). The limit is 5 queries per /24 network per second.
FYI.
