The advised action is to edit this file and activate nearest or
suitable mirrors by removing comment sign ( # ) in front of
the relevant mirror .
During package install , this file is used and traversed up to
an available mirror , when a mirror fails from beginning .
.................
In FreeBSD , pkg_add
http://svnweb.freebsd.org/base/head/usr.sbin/pkg_install/add/main.c?view=markup
the ONLY package site is taken by
getpackagesite(void)
from
if (getenv("PACKAGESITE"))
which it is ONLY ftp.FreeBSD.org .
When the statement
if ((packagesite = getpackagesite()) == NULL)
fails , it is necessary either to wait up to a working state of the
ftp.FreeBSD.org
or edit the "PACKAGESITE" environment variable up to a success which
is NOT an expected action from the beginners .
Instead of this , it is possible to use a pkg_add.conf
and insert into a list of ALL available ftp.*.FreeBSD.org sites
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/mirrors-ftp.html
AND
OTHER mirror ftp sites synchronized by central FreeBSD ftp sites .
Every site will be commented out , but
ftp://ftp.FreeBSD.org...
will be available .
For example :
---------------------------------
# From
# http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/mirrors-ftp.html
:
# The official sources for FreeBSD are available via anonymous FTP
# from a worldwide set of mirror sites.
# The site ftp://ftp.FreeBSD.org/pub/FreeBSD/ is well connected and
# allows a large number of connections to it,
# but you are probably better off finding a closer mirror site
# (especially if you decide to set up some sort of mirror site).
# The adviced action is the following :
# Move the nearest mirror site link to top ,
# and second nearest mirror to second line ,
# up to mirrors suitable to use ,
# AND remove comment signs in front of them .
## Australia
#ftp://ftp.au.freebsd.org/pub/FreeBSD/
#ftp://ftp2.au.freebsd.org/pub/FreeBSD/
...
## Canada
#ftp://ftp.ca.freebsd.org/pub/FreeBSD/
#ftp://ftp2.ca.freebsd.org/
#ftp://ftp3.ca.freebsd.org/pub/FreeBSD/
...
## Turkey
#ftp://ftp.tr.freebsd.org/pub/FreeBSD/
#ftp://ftp2.tr.freebsd.org/pub/FreeBSD/
...
## United Kingdom
#ftp://ftp.uk.freebsd.org/pub/FreeBSD/
#ftp://ftp2.uk.freebsd.org/pub/FreeBSD/
...

ftp://ftp.freebsd.org/pub/FreeBSD/
---------------------------------
This feature and what to do advise will be stated in the release notes .
When pkg_add is started , it will load pkg_add.conf list
into an array , AND traverse this array from element one to
end , last being the ftp://ftp.freebsd.org/pub/FreeBSD/ .
If a mirror site is successful , the package will be installed from this
one ,
and the loop will be discontinued .
The suggested structure does NOT change anything from the new
user point of view .
It is very likely that , experienced users will adhere to
use nearest mirror usage advise to reduce load currently
carried by the default FreeBSD ftp site .
I think , the default ftp site is incurring cost for
internet band width usage .
Then any cost is saved may be transferred to projects to
improve FreeBSD features .
.................
I do NOT know such suggestions are irritative or useful ,
because sometimes it is possible to hear that
"if you do ( or can ) not supply a patch ,
then shut up , ... , shut up"
( where "shut up , ... , shut up" is from "Titanic is sinking" ) .
Thank you very much .

With the new pkgng tool, you can change the ftp site in a configuration
file.
Please also note that the distribution method might change in the near
future (a CDN?).
