Twitch fails to resolve


#1

I’m having trouble resolving www.twitch.tv using 1.1.1.1:

C:\Users\Spatz>nslookup www.twitch.tv 1.1.1.1
Server:  one.one.one.one
Address:  1.1.1.1

*** one.one.one.one can't find www.twitch.tv: Server failed

Using 1.0.0.1:

C:\Users\Spatz>nslookup www.twitch.tv 1.0.0.1
Server:  one.one.one.one
Address:  1.0.0.1

DNS request timed out.
    timeout was 2 seconds.
*** one.one.one.one can't find www.twitch.tv: Server failed

But succeeds using 8.8.8.8:

C:\Users\Spatz>nslookup www.twitch.tv 8.8.8.8
Server:  google-public-dns-a.google.com
Address:  8.8.8.8

Non-authoritative answer:
Name:    twitch.map.fastly.net

Aliases:  www.twitch.tv

Seems to work for me. Do other domains resolve for you via Cloudflare?


#3

Yeah, most of them work fine (including this one).

Might be an intermittent glitch in Tel Aviv, though the datacentre is listed as operational :confused:


#6

Now www.reddit.com fails as well:

C:\Users\Spatz>nslookup www.reddit.com 1.1.1.1
Server:  one.one.one.one
Address:  1.1.1.1

*** one.one.one.one can't find www.reddit.com: Server failed

Note that twitch.tv and reddit.com both successfully resolve (without www. prefix).


#7

Both have their www hosts as CNAMEs of respective map.fastly.net hosts. No coincidence I guess.
