Update 10:30pm HKT: Google Team are aware of it. and seems it is better now.
Update 4/9: Further details from Public DNS issue : “This problem affected CentralNIC hosted gTLDs throughout the Asia-Pacific region”

Since 12noon HKT (UTC+8), Google Public DNS Server (namely, 8.8.8.8) fail to resolve domain with some new gTLDs including .xyz, .blog, .app, .icu from Hong Kong and Singapore.

For example, DNS result with SERVFAIL instead of proper result (like NXDOMAIN as the following example):

# host a.xyz 8.8.8.8
Using domain server:
Name: 8.8.8.8
Address: 8.8.8.8#53
Aliases:
Host a.xyz not found: 2(SERVFAIL)
# host a.xyz 1.1.1.1
Using domain server:
Name: 1.1.1.1
Address: 1.1.1.1#53
Aliases:
Host a.xyz not found: 3(NXDOMAIN)

There are already discussion about this issue on Twitter (https://twitter.com/search?q=google%20public%20dns&src=typed_query&f=live)

After some investigation, some findings are as follows:

• S̶i̶m̶i̶l̶a̶r̶ ̶i̶s̶s̶u̶e̶ ̶h̶a̶p̶p̶e̶n̶ ̶f̶o̶r̶ ̶m̶o̶s̶t̶ ̶(̶b̶u̶t̶ ̶n̶o̶t̶ ̶a̶l̶l̶)̶ ̶r̶e̶g̶i̶o̶n̶s̶,̶ ̶j̶u̶s̶t̶ ̶n̶o̶t̶ ̶a̶ ̶r̶e̶g̶i̶o̶n̶a̶l̶ ̶i̶s̶s̶u̶e̶
  (previous RIPE Atlas measurements were without Recursion Desired bit accidentally)
• quite a lot of new gTLD seems also got impacted by this incident.

Workaround

For the time being, users can switch to alternative nameserver like 1.1.1.1 from Cloudflare.
