Re: [PLUG] [xpost] Cloudflare announces DNS Resolver 1.1.1.1 (on 4/1)

2018-04-10 Thread Skool!lookS 

Without doing much/any testing, from experience I use two different DNS
one from google and other from OpenDNS.

(But I change it if I suspect any latitude depending upon political 
turmoil in country or otherwise.)


This combination helps for me because ISP DNS can play tricks and some 
providers insist their DNS inclusion for service performance.


There maybe forums which are off-limit to ISP DNS but are better 
shielded differently by OpenDNS and likes.


ISP's DNS may get subjected to Govt. whims which isn't necessarily so 
with others above.


Again wherever possible I follow govt. recommendations on deleting 
certain apps on (y)our mobile.  But I have found some of it stupid is 
because govt. itself modified the list later and excluded a couple from it.

Looks like one :) tried to ping 1.1.1.1 no reply.



Ping response is not necessarily a good test.  After all, many servers
are configured to drop ICMP echo request to avoid DDoS.


I did end user testing over the weekend.

Equipments & softwares used as follows =  Ubuntu 16.04 , Mozilla &
Chrome browsers, HP i5 powered latest gen laptop, 2mbps broadband
connection over RJ11, TP Link wifi router with 1.1.1.1 manually fixed
DNS, performed rounds of tcpdumps to ensure all traffic is using
1.1.1.1 DNS server, confirmed speed over sppedtest before proceeding

My observations as follows =

- Indian web-sites take lot of time to load for example zee5.com.
- Few services gave location unknown error
- Browsing of YouTube video's was ok but not that great [Not streaming
but loading list of videos while scrolling]
- Facebook,twitter,linkedin browsing was slow
- Overall web browsing slowed down & in later stage died loading basic
search engine pages like bing,duckduckgo.
-  AWS dashboards & console took significant time to load
- Not frequently used/accessed web sites like slack.com died loading
several times in multiple browsers

Conclusion =

  After switching to ISP's DNS, everything got resumed as expected.

While I have not done such extensive "study", I have reached the same
conclusion over the years.
I use GoogleDNS as a backup, but generally switching "back" to ISP's DNS
improves things a lot.

I would be interested to know why (and if there is anything we can do)

There's a post on Medium [1] which compares the performance of DNS
Resolvers and CloudFlare comes up to be the winner in almost all the
