Something is wrong with routing/steering since yesterday
Yesterday (Sunday) I felt something wasn't right with the "snappiness" when I browsed, so I checked my DNS and noticed my two servers I'm always are connected to had been changed.
When I do a "dig dns nextdns.io" I noticed I was redirected to new slower DNS-servers.
steering.nextdns.io. 60 IN A 217.146.31.87
steering.nextdns.io. 60 IN A 146.19.3.129
When I do the the same dig-query to other DNS-services, I still got the best/fastest servers 188.172.192.71 and 192.36.27.86. Have been connected to these Ultralow-servers for years, but not any more. What makes the steering suddenly change?!
dns.nextdns.io. 300 IN CNAME steering.nextdns.io.
steering.nextdns.io. 60 IN A 188.172.192.71
steering.nextdns.io. 60 IN A 192.36.27.86
;; AUTHORITY SECTION:
steering.nextdns.io. 300 IN NS ns1.nextdns.io.
steering.nextdns.io. 300 IN NS ns2.nextdns.io.
I also noticed it says I'm not using AnyCast when I do a "test.nextdns.io", but when doing "ping.nextdns.io" it says I use Anycast 2. Very weird...
"status": "ok",
"protocol": "DOH3",
"profile": "xxx",
"client": "xx.xx.xx.xx",
"srcIP": "xx.xx.xx.xx",
"destIP": "188.172.192.71",
"anycast": false,
"server": "anexia-cph-1",
■ anexia-cph 3 ms (anycast2)
edis-cph 4 ms
anexia-osl 10 ms
zepto-osl 11 ms
anexia-sto 32 ms (ultralow1)
zepto-sto 38 ms (anycast1, ultralow2)
The connection (3 ms) is great, but the DNS results returned are much slower. When sniffing DNS-queries they usually are 6-15 ms, but today most are suddenly in the range 30-60 ms. You didn't do any infrastructure upgrades/changes during the weekend?!
