It seems that 8.8.8.8 doesn't repond to HTTP. How about example.org which
is reserved by RFC ?

In the USA:
$ ping example.org
PING example.org (93.184.216.34) 56(84) bytes of data.
64 bytes from 93.184.216.34: icmp_req=1 ttl=52 time=5.82 ms
64 bytes from 93.184.216.34: icmp_req=2 ttl=52 time=5.25 ms

$ ping google.com
PING google.com (216.58.219.14) 56(84) bytes of data.
64 bytes from lax17s03-in-f14.1e100.net (216.58.219.14): icmp_req=1 ttl=54

$ ping yoctoproject.org
PING yoctoproject.org (140.211.169.56) 56(84) bytes of data.
64 bytes from yocto-www.yoctoproject.org (140.211.169.56): icmp_req=1 ttl=53

64 bytes from yocto-www.yoctoproject.org (140.211.169.56): icmp_req=2 ttl=53 
time=26.0 ms

The example.org is faster than google.com and yoctoproject.org.

In China, example.org is also OK.
$ ping example.org
PING example.org (93.184.216.34) 56(84) bytes of data.
64 bytes from 93.184.216.34: icmp_seq=2 ttl=52 time=155 ms
64 bytes from 93.184.216.34: icmp_seq=3 ttl=52 time=158 ms

$ ping google.com
PING google.com (216.58.221.142) 56(84) bytes of data.
[no respond]

$ ping yoctoproject.org
PING yoctoproject.org (140.211.169.56) 56(84) bytes of data.
64 bytes from yocto-www.yoctoproject.org (140.211.169.56): icmp_seq=3 ttl=49
