Hi,
I am sorry for you inconvinience about cvsweb.NetBSD.org.
It received the massive parallel accesses and they cause extremely high
load average.
I have added such abusive remote hosts to the filter and adjusted
some QOS and anti-DOS parameters to detect and reject such access.
However all my attempts failed.
bad@ suggested me use of www/anubis and I have added anubis
in front of cvsweb.NetBSD.org.
As side effect, http://cvsweb.NetBSD.org/ is no longer available sadly.
All accesses for pages under http://cvsweb.NetBSD.org/ will be redirected to
https://cvsweb.NetBSD.org/.
After introduction of anubis, the load average was desreased to 1/100.
I checked availabilities from my home network, my cell phone networks
and my day job network. And I do not have a problem yet.
If you cannot use https://cvsweb.NetBSD.org/, please provide me
with description adout your problem.
Thank you.
