Description Jacob Lifshay 2021-07-29 07:05:34 BST
the website is slow for me, so I tried pinging libre-soc.org:
jacob@jacob-desktop:~$ ping libre-soc.org
PING libre-soc.org(libre-riscv.org (2a00:1098:82:f::1)) 56 data bytes
64 bytes from libre-riscv.org (2a00:1098:82:f::1): icmp_seq=1 ttl=43 time=171 ms
64 bytes from libre-riscv.org (2a00:1098:82:f::1): icmp_seq=2 ttl=43 time=170 ms
64 bytes from libre-riscv.org (2a00:1098:82:f::1): icmp_seq=3 ttl=43 time=168 ms

Seeing no issue there, I tried pinging using IPv4:
jacob@jacob-desktop:~$ ping -4 libre-soc.org
PING libre-soc.org (46.235.227.77) 56(84) bytes of data.
^C
--- libre-soc.org ping statistics ---
16 packets transmitted, 0 received, 100% packet loss, time 15359ms

I got the same failure pinging through a different network.

i've enabled cgroups to bring CPU usage down after a simple clone of
the soclayout repo (120 mb download) was discovered to take CPU load
well over 1.7.

anything running under fastcgi is now only permitted 40% CPU,
which approximately multiplies the completion time of any requests
by 2.5

Ok, it's still not accessible over IPv4 though...if that's intentional (I hope not, lots of people still can't use IPv6) please remove the IPv4 address from DNS. Otherwise, please fix the IPv4 accessibility problem.

that is incorrect.

http://46.235.227.77

$ traceroute -n 46.235.227.77
...

there is no problem with either HTTP or HTTPS,  so that is misleading.


$ telnet 46.235.227.77 80

it responded, therefore is functional.

there is no IPv4 accessibility problem.

not a high enough priority to warrant investigating the ping packets.
traceroute is fine.

closing permanently.
