I see an unexplained latency when using the 184.108.40.206 & 220.127.116.11 DNS servers.
$>time dig www.microsoft.com
; Query time: 52 msec
;; SERVER: 18.104.22.168#53(22.214.171.124)
;; WHEN: Wed May 22 00:39:51 IST 2019
;; MSG SIZE rcvd: 128
real 0m1.062s /*+1 sec delay visible */
This is true for any domain when using these DNS. When I switch to my local ISP DNS things are superfast:
@>time dig www.microsoft.com
;; Query time: 2 msec
;; SERVER: 126.96.36.199#53(188.8.131.52)
;; WHEN: Wed May 22 00:40:31 IST 2019
;; MSG SIZE rcvd: 565
Is this the local ISP messing around or something else? the odd thing is that query time is in ~50msec always yet total time exceeds 1sec. Browsing is badly affected with browser displaying “resolving host” routinely.
Thanks for any tips on tackling this.
