[afnog] CloudFlare DNS 1.1.1.1

[Loganaden Velvindron]

Hi folks,

I'm playing around with 1.1.1.1 from .mu. Cloudflare has a PoP in .mu,
but right now the high latency indicates that the traffic is going
through international links for DNS.

traceroute:

However, web traffic is going through their PoP :

After talking to the Cloudflare folks, they hinted that deployment is gradual.

I thought that it would be nice to see how 1.1.1.1 is doing around the
Cloudflare PoPs in africa. I use RIPE Atlas to send pings to 1.1.1.1,
based on regions where both RIPE Atlas probes and Cloudflare PoPs are
present: durban, jnb & kenya.

I parsed the json output using jq:

    "avg": 2.8788183333
    "avg": 1.0449133333
    "avg": 1.95606
    "avg": -1,
    "avg": 46.1442483333
    "avg": 0.7843883333
    "avg": 2.0959066667
    "avg": 52.822845
    "avg": 23.4972033333
    "avg": 317.121765,
    "avg": 25.8255783333
    "avg": 3.00995,
    "avg": 49.6507816667
    "avg": 2.0425866667
    "avg": 4.4146666667
    "avg": -1

8 out of the probes have < 5 ms latency, while 5 of the probes have
latencies > 20 ms. This indicates that many of the CloudFlare PoP can
serve DNS.
