I have been considering using a new DNS server which was written up in USA today, quad9. They do threat analysis and block nefarious sites. Yesterday morning I was doing some pinging of quad9 and Google DNS on Colorado central telecom. I repeated the ping tests after the Cielo install.
They show that Cielo has 2 to 3 times the latency, and a lot more jitter. I wonder if this could be related to DSLReport bufferbloat grade of 'F'.? Probably not, I doubt if ICMP packets are buffered.
The good news is there's no packet loss. (DSL Report Quality 'A+')
The following are the summaries of each ping session.
CCT:
Google DNS has astoundingly short latencies and almost no jitter. (Longer ping sessions showed the same but they were no longer in my terminal history)
--- 8.8.8.8 ping statistics ---
6 packets transmitted, 6 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 12.419/12.555/12.650/0.092 ms
--- 9.9.9.9 ping statistics ---
1926 packets transmitted, 1926 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 44.639/45.480/73.270/1.269 ms
CIELO:
